Ass Rocket Race!!!!
What we do is strap heavy duty bottle rockets to the cast's respective asses. Their pants will have padding of cource. We then stick them on skateboards and light the rockets and see how far they'll go. To make this more fun they dress up like whatever they want to. This should be funny due to the painful reactions from the cast when the rockets explode. Its not like the cast isn't used to things blowing up in there ass right?
