NBA referee Joey Crawford is known as many things by basketball fans...and none of them are very nice. Can you blame them? Crawford once ejected Tim Duncan from a playoff game for smiling while on the bench (which eventually led to a suspension for Crawford).

The point is, the man has an irrational temper which is fueled by his whistle. Check out what he did to this poor ball boy in Philadelphia. Apparently the kid didn't wipe the floor clean enough, prompting Crawford to call in backup and give the ballboy a mean stare. Word is he nearly ejected the ballboy.

Who would eject a ballboy for not mopping the floor hard enough? You already know the answer to that question.
