During the New York Jets' training camp on 'Hard Knocks' (Wed., 10PM ET on HBO), fans start getting a little overzealous. After a great play, one rambles onto the field with his arms up. He won't move. "Look at this dude on the field, man, he is trippin'," says Jets cornerback Marquice Cole. "Where the police at, man?"

Two security guys come out. At first he dodges their grasp. Then they throw him down on the ground like they know a thing or two about how to tackle.

The crowd starts cheering. "Hey, give it up, man, for the guy that ran on the field like a jacka--," says Cole.
