22. Amare Stoudemire
Sometimes temper tantrums cloud people’s judgment. This was definitely the situation in the case of Stoudemire because he made a very dumb decision after a New York Knicks playoff game. The Miami Heat inflicted a crushing loss on the Knicks in the second game of the series and Stoudemire wasn’t impressed. He decided that the appropriate course of action was to unleash his fury on a nearby inanimate object.

So he hit a fire extinguisher. It emerged that this wasn’t a good move because his hand immediately gushed blood and paramedics had to help him. He missed the third game of the 2012 series but avoided serious damage. However, it is never a good idea to hit walls, windows, or anything hard in the nearby vicinity. Stoudemire discovered this to his cost.
