Saturday Off-Topic, but really, *really* fun:

Zenyatta is a six-year-old, unbeaten Thoroughbred that I'd never heard of until today. She has a signature dance and an unusual racing style. Watch this: you can see her using that great. Big. Butt to get speed right near the end. She's an enormous horse with a lot of power, and seems to completely enjoy what she's doing.

I'm not a huge fan of horse or dog-racing, but damn if it's not fun to watch the good ones really get into what they're doing.
