The Worst Error You've ever made reffing a game?

[Toren]

But I remember distinctly two calls:

First: player goes in for a layup, lays the ball of the glass, defender tries to block it and hits the backboard. The backboard rattles as a result and here comes my whistle...tweet, goaltending. At the time I blew, I knew it wasn't a violation, but I didn't have much experience with above the rim plays, so I blew. Nobody said a word. Luckily enough it was a blow out game.

Secondly: Player A shoots the ball, Team B goes up to secure the rebound, before they grab the ball, Player B gets fouled. Team B is in the bonus. I call the foul, don't award the shot. What makes this worse, is I explained to the coach, "there is no team control on a shot, so that's why you don't get to shoot free throws"...wow, precisely inaccurate is how I would describe that
