Hat Simulating Fried Egg
Contrary to what you might think, there's a market for a wide array of useless inventions. People impulse buy for a variety of reasons: they see something they've "always wanted," they're on vacation, their favorite team just won, or because something is just crass enough to be hilarious. However, there are some things that no sane person would buy, and a fried-egg-shaped-hat is one of them. Patented under the compelling name of Hat Simulating Fried Egg, you can view the drawings of this hideous headware here. The patent listing provides some engaging reading, particularly this line:
"The hat finds utility, for example, as an attention-getting item in-connection with promotional activities at trade shows, conventions, and the like."
And to promote anti-drug campaigns, apparently. Go figure. Anyway, our favorite Hat Simulating Fried Egg illustrates that if the very name of your product provokes the question why on earth would someone want that, there's probably not a market for it. Useless objects should have something appealing about them to get customers pulling out their wallets.
