If you guys have not heard or seen this yet, it's worth checking out. It's pretty funny. Basically the story is this guy was in the front row making it rain (for those who don't know that means throwing money around like you would do at a strip club). Pitbull apparently told him not to do that because he was bothering him. So when the guy didn't stop, Pitbull brought him on stage and let a nice little one hitter quiter rain on the guy right back.
there are longer versions, but this one gets right to the point.
