If you love stand-up comedy shows and are proud of your mad heckling skills, you might want to think twice before opening your big mouth at the upcoming Katt Williams performance.

The comedian, who also acts and raps, does what most comedians do in a heckling situation: He uses the mic to lob a comeback that takes the heckler down. Williams, however, has been known to take it to the next level, getting into the crowd to get up close and personal with mouthy interrupters. The multitalented and funny Williams has done several stand-up specials, including The Pimp Chronicles and Priceless: Afterlife. You may know him as Money Mike in Ice Cube’s Friday After Next and Next Sunday movies. He’s hilarious. Keep your comments to yourself
