I've got the biggest balls of them all..

What's the deal with all the nut grabbing and ball punching going on in the NBA playoffs this year? A couple of days ago Jason Terry punched Michael Finley (see video above) in the balls while wrestling for the other ball on the floor.. And of course a few weeks ago we had Reggie Evans violate Chris Kaman's balls during a game. I guess theres just a fascination with balls in the league right now.
