The jingle showing the "Don't Mess Around With Me" logo played one last time as Marcus ran back into the camera shot.

"Welcome back to the final part of Don't Mess Around With Me". The audience whooped. "And both games we've seen have led up to this moment. We have our two losers, they've both been messed around with, but one's going to get an extra big mess before they head home tonight. So let's welcome them back out shall we! Give it up for Christian and Joey!"

A screen behind Marcus slid open to reveal Christian and Joey, both cleaned up and looking remarkably refreshed. The gunge and mess that coated them when they were last on stage had disappeared and they seemed to be much more comfortable with being on stage now that they had already been trashed. The stage crew had given them tight-fitting t-shirts to wear (Christian's black, Joey's white) and grey sports shorts to wear as neither knew they would need to bring a second change of clothes.

Both contestants stood on either side of Marcus onstage. "Christian, how are you feeling? Last time we saw you, you got dumped on with week-old gunge, rotten eggs and fish guts."

Christian blushed and ran his fingers through his perfectly messy brown hair. "Yeah, I've had better experiences. But I'm hoping that was the only time I'm going to be getting messy today as I spent ages perfecting my hairstyle again after that."

"And you Joey, you were so close! Two seconds faster and it would have been Dan standing here!"

"I know, I'm so annoyed I popped all the balloons as I probably would've been third then. Maybe even second!"

"Alright Joey, don't get ahead of yourself!" The audience laughed. "And how did it feel to get pelted with 10 pies?"

"I think I might have preferred the pies to all the gunge. Although, I definitely looked like a weird snowman afterwards."

At this point, Marcus pointed out to both Christian and Joey, as well as the audience, that the other four contestants from the show now sat in comfortable seats in the front row of the audience. Dressed in dressing gowns, they looked much more relaxed and comfortable than the two contestants onstage.

"Okay, so what's the final game, and more importantly, what's the final mess? Well, I'm going to give you both a choice to sit in one of two carts: the spotty cart and the stripy cart. These carts are set on a track that goes around both this studio and the mystery one next door. In one of the carts, there are two buttons: Button A and Button B. In the other cart is an envelope, in which will be written 'A' or 'B'. Now, the person with the envelope will, at this point, know which button will set off their cart around the track. They have to convince the other person, in the other cart, to press the other button, which will set them off around the track. It's a game of bluff, and as you can imagine, there's a lot of mess if you go around this track."

Marcus asked the two boys if they understood the rules of the game. They both nodded nervously. The studio lights dimmed as tense music started to play as the three of them walked over to the carts at the edge of the studio. At this point, you could see the two tracks the carts were set on had a barrier in front of them preventing them from going around the track that went all around the studio and through a mystery door at the other end.

"As Christian played first tonight, he will choose which cart he would like."

Christian looked at both carts carefully. He couldn't see what was inside of them, but he knew that he wanted to know which button meant which. He then remembered he was wearing a striped top in the first part of the show, and that didn't bring him much luck.

"I'll take the spotty cart, Marcus."

"Okay then, that means you're in stripy cart Joey. Please go and take your seats."

The two boys walked to their respective carts and saw what they had chosen: Christian had indeed picked the cart with the envelope in it, whilst Joey was greeted by two buttons with a massive 'A' and 'B' on each of them.

From where they were sat now, they realised that they had no idea what could be meeting them if they got this wrong.

Christian opened his envelope, but under the instruction of Marcus, did not reveal to anyone the contents of it. "Christian, you may now talk to Joey and let him know which button he should press. Joey, feel free to ask any questions to Christian to decide which button you should press. You will have three minutes to make your decision."

Christian and Joey locked eyes. Neither wanted another shower and the embarrassment of being gunged twice on TV.

"What button do you want to pick?" asked Christian.

Joey was confused. "I don't know. I want to pick the one that sends you down there. I want to hear what you have in that envelope."

"But if it was totally down to chance, which one would you pick?"

"I'm not sure. Maybe B?"

Christian slightly opened his lips in nervousness at this. He paused and had a look full of thought on his face. "The button that sends you to be gunged in Button B."

Joey's eyes widened. He looked and studied Christian's face for any signs that he was lying. "Are you playing with me?"

"I'm not, the button that gets you gunged is B."

"But you could be messing me around here."

Joey leaned back with an anxious breath. "Okay, I'm just thinking out loud about what I would do in your position. If I knew that I would get gunged with Button A, I need to get you to press Button B. But telling you to press Button B would get me to press Button A, which would end up with me getting gunged." Joey continued like this for another two minutes, with Christian occasionally chiming in by saying "I'm telling the truth" and "if you press B, you'll get gunged."

A klaxon rang out. Marcus then reappeared. "Joey, it's time to make your decision. Is it going to be Button A or Button B?"

Joey held his face in his hands. He looked at the two buttons staring at him, looked at Christian, and then looked at the buttons again. Then, he pushed Button A.

Immediately, the lights came up and sparks flew out around the stripy cart. The barrier in front of Joey's cart lowered and, it slowly started rolling forwards. Christian let out a huge cheer and showed that the letter inside his envelope was 'B'.

Joey shook his head as both tracks merged into one. The cart arrived as its first stop, where Marcus was ready to provide commentary.

"Oh dear, our biggest loser of the night is Joey!" The audience cheered. The mess was about to start. Stood next to Marcus was Oscar, who went up against Christian in the first game, and he had a big plunger in front of him. "Now Joey, as our big loser, it doesn't seem fair that you miss out on anything that your last opponent went up against." At this point, Oscar pushed down on the plunger and, from above, Joey got drenched in murky blue slime. Joey was okay for a few seconds, but then the smell hit him and he realised what else was in the slime. "That's not just normal slime," Marcus gloated, "but that's everything that Christian got earlier: rotten eggs, fish guts, custard, baked beans, mud and nacho cheese." The cascade came down and down for 15 seconds and at the end of it, Joey already looked like a mess. He got a cheer from the crowd and then the cart started moving forward again.

The cart rolled along the tracks, around a bend and through the mystery door. At this point, the studio audience could see what was happening with some screens in the main studio and Marcus helped with some narration. "Okay Joey, you're now entering the mystery studio. First up is a trip to the Builder's Den."

The first set looked a bit like a building site. There was a cement mixer, wheelbarrows, scaffolding and Robbie stood there dressed in a builders outfit. As the cart stopped at the next buffer, Joey noticed the grin on his face.

"Okay Joey," Robbie announced, having practised these lines in the shower whilst removing green gunge from his privates, "you're about to get the builder's treatment. The first thing you need to know about builders is that they use cement...a lot of cement."

At this point, Robbie revealed a big red button in one hand. With the other, he smashed it and a gunge gun splattered Joey in grey gunge that looked just like cement. It was aimed right at his face and took him by surprise. Once it stopped, Joey's jaw was hanging from his face.

"Next, we know that builders have to think very carefully about what they build. It might even involve digging up the mud."

Robbie pressed the button once again and this time, thick lumpy mud dropped down on Joey from above. He tried to dodge, but this caused all the mud to pool in his crotch, which became more and more uncomfortable for him. Eventually, he decided to lean forward, and the mud soon pushed the grey slime into the bottom of the cart.

"And finally, we all know that builders love their tea. But how big do you like your tea, Joey?"

Robbie put down the button, picked up a bucket and aimed the cold tea that had filled it at Joey's face. It splashed all over, slightly washing away some of the slime and mud so it looked like Joey had just emerged from a sewer. Joey wiped his eyes clean and laughed. He had accepted his fate. The audience applauded as they realised what a good sport he was being.

The buffer dropped and the cart moved along the track. "Up next," Marcus announced on the tannoy just as Joey was going through the next door, "we have our own version of Wimbledon." This set was made up to look like a tennis court, with the markings on the floor and the walls having pictures of a fake crowd. Also in the room was Dan, dressed in a white sports top and white shorts. He was carrying a basket.

He had also been given a line to say: "Let's see how to you handle these serves Joey!" At this point, he revealed small green water balloons and he started throwing them at Joey. Joey dodged initially and Dan missed, but he got him the second time on the shoulder. As the balloon exploded, it splashed yellowy, green slime on him. Joey did his best to try and avoid the slime balls coming his way, but on his eighth attempt, Dan managed to get him on the head and Joey's face became coated in slime.

The cart rolled on as Dan did a good job of covering Joey in slime. Eventually, the cart stopped at the next buffer and Dan had run out of balls to throw. "That's game, set and match," Dan told him, "but Wimbledon wouldn't be Wimbledon without some strawberries and cream!" At this point, four cannons started aiming gunge at Joey: two were red, two were white. They coated him and the colours began to mix as they landed on him, so he started looking like a paint palette from white to red, with a lot of pinks. After a little, they stopped and Joey managed to catch his breath. On him, there were no remnants of the tea that he had been doused in mere moments ago. He realised that each phase was getting bigger and messier as it went along. The buffer released, the cart rolled on and the audience cheered him on as encouragement as he went into the next section.

This room was decorated with blue skies and clouds. A model lighthouse was in a corner, and the sea adorned one of the walls. The ground underneath the track was very sandy. Marcus came back on the tannoy to say "I hope you like the beach Joey because that's your next destination". Dressed in nothing but his beach trunks, Lewis stood to the side of the buffer that Joey's cart stopped at. He too had lines he had to say.

"Okay Joey, I don't know about you, but no trip to the seaside is complete without some fish and chips." The audience oohed, having an inkling of where this is heading. "The first thing we need to do is batter our fish. But I can't see any fish here...so I guess we'll use the next best thing." It came as no surprise to Joey that batter descended upon him from above the cart. It was thick, much thicker than the gunge that had been used so far, and it weighed him down a bit. The red and white gunge slowly made its way down his body onto the bottom of the cart, sped up by the fact that Joey had decided to look into the batter (it was something that he had always weirdly enjoyed the taste of).

Laughing, Lewis revealed, "well, I really like my fish and chips with some mayo and ketchup". At this point, Oscar, Robbie and Dan appeared, still in their costumes, with bottles of ketchup and mayonnaise. Lewis had his two bottles too, and they started squirting the contents of them at Joey.

"Ah, it stinks!" Joey screamed, much to the amusement of the other lads, who just aimed the ketchup and mayo as close as they could to Joey's nose. Joey started trying to flick the shots of sauce away but it was no success, and soon he was covered in white and red streaks once again.

"Finally," Lewis said, composing himself after laughing so hard, "when it's a hot day, there's nothing more refreshing than an ice cream." Joey's eyes widen. Everything so far had been pretty unpleasant, but nothing had been cold.

"Whether it's mint choc chip..." Lewis continued, just as Oscar picked up a bucket and poured melted mint choc chip ice cream all over Joey's head. Joey yelped as the cold cream hit his head, which caused all the other lads to laugh again. "...or strawberry," at which point, Robbie poured a bucket of strawberry ice cream over his head, "...or vanilla," and Dan poured vanilla flavour over his head, but to be extra cheeky, he pulled open the back of Joey's top and poured some down there. Joey at this point shrieked, leaning backwards and making it easy for Dan to get a good faceful of ice cream on there. "Or finally, there's always chocolate." Lewis picked up his bucket of chocolate ice cream, pouring the thick brown liquid over every inch of Joey's body. All four lads laughed, and Joey eventually joined them. The buffer was removed and he went through the final door on the cart.

As he went through, he saw the studio audience on their feet cheering him on. Thankfully, he also saw the end of the track, where Marcus and Christian were standing. He looked at the bottom of the once striped cart, and it was a cocktail of remnants of cement, ice cream, batter and slime. If that's what the bottom of the cart looked like, Joey had no idea how messed up he looked.

The cart stopped at the end of the track. "Joey, your ordeal is nearly over," Marcus announced, "but first, tell us, how was that?"

Joey continued to try and wipe all the muck from his face. "Well, I thought earlier was bad, but that was another level." He then smiled. "But you know, that was really, really fun!" The audience cheered!

"Well, you've proven yourself a good sport, but there's one messing up we have to do, and that's courtesy of Christian. Now, do you remember earlier when you said preferred pies to gunge?" Joey laughed. He wondered if that statement was going to catch him up. "Well, it seems fitting that we have five other contestants with two hands and that makes up ten." Marcus then turned to the audience. "SHALL WE PIE HIM 10 MORE TIMES!"

The audience whooped and Joey smiled. The pieings had been his favourite part of the day, so to get them now was no torture at all. All five lads lined up with a huge pie in each hand, with Christian first. "Suffice to say, better make the right choice next time." As Christian pushed the first pie into his face, Joey smiled to himself. He had made the right choice, and he loved every second of being messed up. And as Christian pushed the second pie into his crotch, he also felt a twinge that he might have been enjoying this in another way too.

He wiped the cream away from his eyes and saw four more men carrying pies walking towards him. This was the perfect way for him to end his messy day.
