For a wacky game, challenge teams of guests to design their own snow guys.
The Setup: Begin this giggle-inducing contest by dividing kids into teams. Send them to different rooms, where they'll find toilet paper, piles of hats and scarves (the funkier the better!), buttons cut from construction paper, and tape.
To Play: Each team must transform one of its members into a snowman, then help their creation get back to the central party room with as little "melting" as possible. Award prizes for wackiest outfit, best teamwork, and so on.
