You cannot display a hypnotized person in a storefront window.

The Law Explained

In the late 19th and early 20th centuries, stage hypnotists and snake-oil salesmen would place a 'hypnotized' subject in a shop window to draw massive, sidewalk-blocking crowds. The city of Everett banned this specific practice to prevent traffic jams and maintain public decency. No matter how good the trance is, you have to do it behind closed doors.
