Ali Bongo's Growing Hat by David Charles and Alan Wong
One of the best comedy props for kid show performers. The magician shows a paper hat to the children in his audience and the volunteer on stage. The hat, according to the magician, is too small for his volunteers head. To make up for that fact, the magician unfolds the hat, making it larger. The magician continues unfolding the hat until it completely covers the volunteers head! For a final gigantic laugh, the volunteer turns around to show a large goofy face printed on one side of the hat.
