Tried to put up a picture of Andre Agassi, but couldn't complete the process (Safari couldn't open the page to post it).

Do you play tennis?

Tennis would be nice "commando" sport?

Just makes sure the ball doesnt hit your balls

That would create quite the racket?

Yes it would...

OK, let me try to upload the tennis shot again...

Here's a page of tennis players:

Wow, tennis! Brings back a fond memory from my youth -- lol.
Freshman year in college, I was "back home" one weekend, staying with a friend (he was a year younger, HS senior then). One afternoon the two of us went to his community tennis court to play a few. Right in the middle, he suddenly (for no apparent reason that I can recall) dropped his shorts and kicked them aside, and resumed playing in his tightie whities! Needless to say, my play suffered, as I was quite distracted (maybe THAT'S why he did it! lol). He stayed in his undies for probably about an hour! Was quite hot, as he was very cute and had a nice body.
