Close down a street (preferably one with a steep hill.)
Park a truck, filled to the brim with bouncy balls, on top of that hill.
Get the guys in front of the truck and let them choose any mode of transportation, each a different one. (e.g: skateboard, shopping cart, bike, bunny suit, ...)
Tilt the truck and start the race (whoever arrives first at the bottom of the hill wins)
(sorry there is no poo in this one, but it will be sweet in 3D, trust me!)
