and don't forget:

Finally came the show-stopper before the race. When Wallace announced her name in the post parade, Zenyatta did something she never had before.

"Has anyone ever seen a horse bow before a race?" said trainer John Shirreffs' wife, Dottie. "She bowed twice when she was announced."

"I thought I'd seen it all with her, but I'd never seen her do that," said Smith.

She now has songs written about her. They gave away sets of glasses with her picture on them. One man stood in a long betting line and ordered 20 win tickets on her, $2 each. When he left the window, he said he bought them not to cash, but to send to family and friends.
i bet no one ever thought of buying keepsake tix before.
