Balloon Stuff
For this game you need teams of three or four. 1 person is the "stuffy" and the others are the "stuffers". The "stuffy" puts on an oversized t-shirt, the "stuffers" are given balloons. The object is for the "stuffers" to blow up balloons and stuff them under the t-shirt of the "stuffy". The team with the most balloons under the shirt in a given time wins!
