Bring out a little tiny briefcase. The kind people use to carry their business cards. Less than a half-inch thick. Explain that you would much rather be golfing than working. Open the briefcase and remove a real, solid golf ball. The ball is so much bigger than the briefcase, their eyes will pop. You can immediately show both the inside and outside of the little briefcase. In addition to the golf ball production, George give you several other routines and effects using Just In Case.
