4. Amare Stoudemire (2012)
The Knicks met the Miami Heat in the NBA playoffs and lost the first two games of the series. They needed all of their players to step up and be counted but Stoudemire didn’t receive the memo. A wave of fury washed over the basketball star but he didn’t just take a deep breath. No, he decided that the best way to deal with his anger was to punch a fire extinguisher.

This was a terrible idea because extinguishers are a lot harder than the average human hand. He required 15 stitches in his hand after the ridiculous incident (via CBS Local). Luckily, it was his left hand so he didn’t worry about his NBA future. But it was still a terrible decision and also cost his team dearly as they lost the series. Maybe they would have gone out anyway, but his absence didn’t help.
