Over ten years ago, Tool was touring in support of their album Ænima and during a performance of 'Pushit', a fan jumped up on stage. After that, vocalist Maynard James Keenan, who by the way, is trained in Brazilian Jiu-Jitsu, slammed the fan to the ground and put him in a chokehold. The best part about it, is that Maynard continued to sing the song.

Below are videos of the Maynard/Fan clash!
