I went to highschool with some kid who was a "sponsored amateur" skateboarder. I can't for the life of me remember his name, but there is a pretty good chance he went pro. One day he was skating in front of the school with some fat friend of his. Me and a buddy stopped to watch, after a while my friend said "ok, let's go".  And I said I wanted to wait to see the other guy skate as well. My friend said "no, he sucks, let's just go".  I asked my friend if he had seen him skate before and that's how he knew he sucks, he said "no, but he's fat. Fat people always suck at skateboarding".  So true.
