ANDY RODDICK BETWEEN THE LEGS SHOT

Does it take big balls or no balls to pull off the in between the legs tennis shot? Because I'm thinking if you have big ones then you don't want a piece of solid graphite/titanium/whatever the fuck they make out of racquets these days swinging between your legs so close to your junk. But if you have no balls then go ahead and swing away. Brooklyn Decker could give us a solid answer. Or Roddick's boyfriend. Things that make you go hmmm.
