Does My Bum Look Big In This?

I like Serena Williams' healthy attitude:

The defending Australian Open champion yesterday insisted she was fit and ready to play, but expressed disbelief at pictures of her taken from behind.

"I saw one of me running and I was like, wow, my hamstring is that big?" Williams, 24, said. "I had no idea my muscle was like that."

I'm going to use that one.
