Michael Richards (Seinfeld's Kramer) Loses it and apologizes!

Michael Richards exploded in anger as he performed at a famous L.A. comedy club last Friday, hurling racial epithets that left the crowd gasping.

Richards, who played the wacky Cosmo Kramer on the hit TV show "Seinfeld," appeared onstage at the Laugh Factory in West Hollywood. Kyle Doss, an African-American, said he and some friends were in the cheap seats and he was playfully heckling Richards when suddenly, the comedian lost it.

The camera started rolling just as Richards began his attack, screaming at one of the men, "Fifty years ago we'd have you upside down with a f***ing fork up your ass."

Here's the original video:



Here's the public apology:
