Stage Crasher Runs Amok at Jonas Bro Show

A rabid male fan crashed the stage at a Jonas Brothers concert the other night in Madrid -- but unlike Britney, who infamously screamed when the same thing happened to her, these guys just kept on playing.

The good stuff -- which includes the dude running in circles from security and ripping his shirt off -- starts at the 1:13 mark.
