Lisa and Louise are about to reveal which girl will take on 'The Rubix Cube Timer Challenge' in The Destroyer tank. But, something is not quite right...

The card which was meant to say, Rhianna, as briefed to the hosts by the producers, actually says 'Lisa and Louise' in an unplanned spontaneous prank.

We think contestants Jessica and Rhianna who have been gunged by the devious hosts many times had quite a lot of fun getting them messy, cue gunge blasters, messy jets and a special tank for both girls.

Includes after hours interview where the girls speak about their reaction to it.
