I love watching Serena Williams play tennis. Heck, she can serve a tennis ball 120 mph. That's movin'. But the sounds that come out of her mouth every time she hits the ball are, well ... alarming.

I can't figure out if a.) she's having a tooth pulled; b.) she's hacked off at something her crazy father said; or c.) she's having — how would you say it? — a memorable sexual experience.

Seriously. Watch her at Wimbledon, and you'll understand what I'm talking about.
