When a professional athlete makes a great play, they sometimes swing their fist upward into a traditional fist pump. However, the fist is not supposed to connect with anything other than air. Here is Chicago Bulls forward Carlos Boozer celebrating an "And One" basket by punching referee Danny Crawford in the groin area.

Either Crawford wears a cup, or he's been neutered, or the most likely scenario, Boozer just missed the jewels. Luckily for everyone, Crawford seems to be okay.
