Quality Road's Breeders' Cup Freakout

Quality Road delayed the start of the 2009 Breeders' Cup Classic for 5 minutes when he decided he was NOT going to go into the gate. A few common tricks were used, but when the blindfold was put on and he found himself standing in the gate, he presumably panicked and lost his head, bucking and kicking and trying to bolt. Thanks to the assistant starters, a human hand was always clenched on a rein and he wasn't able to bolt off and run blind (literally) down the track and crash and kill himself.

He was scratched from the race with a cut on a leg, and went down in history as the first (and so far, only) late-scratch in Breeders' Cup history. The horses were reloaded and Zenyatta blew away to win.

I've never seen a gate mishap like this one. It's one thing to see a horse flip over and be lying down in there, but it's quite another when a 1100 horse has lost his head and puts himself and those around him in grave danger in a metal contraption.
