Video: Michael Richards euthanizes moribund career; Update: Richards surprised to discover he's a racist

What’ll the excuse be? Drug dependency? “Exhaustion”? A Gibson-esque three-beer buzz? Or will it be irony?

Extra credit: which lefty blogger will be the first to say Richards should audition for that new right-wing Daily Show?

Update: Pathetic.

Letterman asked Richards if he would have responded to the heckler in a similar vein if he had been of a different race.

“It may have happened,” said Richards. “I’m a performer. I push the envelope. I work in a very uncontrolled manner on stage. I do a lot of free association — it’s spontaneous, I go into character. I don’t know. In view of the situation and the act going the way it was going, I don’t know. The rage did go all over the place it went to everybody in the room.”

Richards seemed baffled by his own reaction on stage.

“I’m not a racist, that’s what’s so insane about this,” he said…

“Having apologized, is there much more that you can do?” Letterman asked.

“I just have to do personal work,” Richards replied.
