Height changes at will.
Willard does but 10 minutes and these he makes interesting. Of nice appearance for a tall fellow and with a smiling personality, he easily talks himself through the act, elevating and lowering his body alongside a uniformed stage hand. Besides which on the drop the Colonial lowered behind the scientific puzzle, were plenty of lines by which those in front could gauge the distance Willard "growed." Willard is a first class vaudeville act, for he's the kind that would make a couple of sweethearts break an engagement arguing on their way home after the show. That's the kind of advertising talk any turn should be tickled to death to create. His "growing" is freaky but it's not fakey and when Willard uncovers some way to move his shoes before an audience, "growing" in his stocking feet (which he can do) the mystery will become stronger. But after all it's the showmanship and Willard has it. No one but a natural showman could get away with a turn of this kind on a regular vaudeville stage.
