Mouth Cage

It is easy to see why this weight-loss contraption did not gain popularity after it was patented in 1982. This cage, which is strapped over the mouth and padlocked, is quite intimidating and would probably frighten small children. The problems, however, are more than cosmetic. While the design prevents its wearer from eating junk food, which is good, it also prevents its wearer from eating anything at all, which is not healthy. Also, what if someone loses the key?
