The Big-Bag Challenge

Needed supplies:
A big, grocery size, paper bag

Open the paper bag and place it in the middle of the floor. Take turns picking it up.
The stipulations are:
You must pick up the bag with your teeth
You must stand on one leg only!
You must not touch your hands to the floor

In the first round everyone gets a turn. If they break one of the rules, they are out of the game. Before the next round, cut one inch off, around the top of the bag.

Continue on, cutting one inch around the top of the bag, each round. The last one to pick it up, wins.
