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

[scrounge]

Called what was in hindsight a completely phantom traveling call on a somewhat-clumsy girl (Girls JV) that fumbled a throw-in. Generally no biggie...except her team was up by 1 point. With 3 seconds left. After a time out, the opposing team throws it from the division line spot to a girl who got free under the basket and laid it in for the winning basket right before the buzzer. An irate mom came out the stands and swung her purse at me, but I saw her coming and ducked away. Oy.

So not really the worst error (there've been PLENTY of WTF ones) but certainly the worst related to the immediate aftermath and consequences.
