L'il Devil's Trick of the Day A Week's Worth Of Whoopee A gallimaufry of gags, the prankster's pantheon. Our seven-day selection of sophomoric stupidity includes a joy buzzer, a bottle of disappearing ink to spill on someone's white shirt, candy that turns to blood in your mouth, a pack of gum with a mousetrap inside, a nice fake nail to put through a finger, a fly-in-the-ice cube, and the American classic whoopee cushion. Add some rubber vomit and you've got enough gifts to get through Channukah.
