TMZ.com is getting a lot of attention (again) — managing editor Harvey Levin is live on CNN right now — for video of comedian Michael Richards throwing around the n-word during a performance at the Laugh Factory on Sunset. The tirade began in response to some heckling by two black guests and went on for about three minutes. TMZ says that most of the audience got up and left, though some were laughing. Richards performed the following night without incident, but Levin says there's going to be a protest of some sort outside the Laugh Factory this morning.
