Here's a funny prank Charles Barkley pulled on teammate Manute Bol back when they played together on the Philadelphia 76ers. I don't want to ruin the shocking ending, so just watch it. And laugh. Update! I missed this the first time around, but Ben Q. Rock (of Third Quarter Collapse) pointed out something that should have been obvious: "Charles grabs his man region with disturbing frequency." Wow. He really does.
This isn't Barkley related, but I'm including it anyway: Last year, Jason Richardson filled former teammate Patrick O'Bryant's car with popcorn. You can tell Patrick was, you know, less than happy about it...but what's a rookie going to do? Other than go home and cry, that is.
