The Stool Jewel
This is very simple but would take a little time. Get a stone or cubic zirconia or jewel of some sort about the size of a gum ball . . . start with one member of the Jackass crew swallowing it and waits until it passes through their system and then they poop it out. When they poop it out, it gets washed off and cleaned and then another Jackass guy does the same thing and then poops it out, and then the next guy and the next guy until every dude in Jackass has swallowed it and pooped it out. Then, the stone is put into some kind of glass case and goes on Jeff Tremaine's mantle.
