An idea for one of the events, a quiz round like in those game shows where it's one on one and first person to answer the question correctly gets to pie the other.
I could see MyPieRogative asking the questions. I could see Ariel and Messy Jessie starting it out and then going to the back of the line waiting for their next turn. Questions would have to be general knowledge questions that anyone from the UK or USA would know.
Well with that attitude Maria as well as that outfit I'm sure your well on your way to becoming a Dame or Lady, I'm sure Elizabeth will see that is the right and proper course of action.
