The Idiot Box
This prank starts with a small plexiglass box (about 12in X 12in X 12in) with a round hole in the top big enough for someones hand/arm. Next, Knoxville goes around collecting the other cast member's valuables (car keys, wallets, phones, etc.) and places it in the box. The kicker is, the box is filled with scorpions. A scorpion sting won't kill you, but who the hell wants to get stung by a scorpion? Knox can then look on in laughter as they try to get their valuable out of the box.
