Jerry Seinfeld, Michael Richards in 'Comedians in Cars Getting Coffee': Memories and Controversies (Video)

The former "Seinfeld" co-stars go for a leisurely drive in California, trading riffs and more sober conversation along the way.

Michael Richards warned Jerry Seinfeld that hanging out together would result in him acting like Kramer. He wasn't kidding.

In the final episode of Seinfeld's web series Comedians in Cars Getting Coffee, the co-creator and star of the megahit sitcom Seinfeld reunited with his co-star, who played his kooky next door neighbor. Richards, of course, is not exactly like the character -- he is certainly smarter, and probably has never painted over the yellow lines on a four-lane highway -- but you can tell why he got the part.

Setting out in a rusted old VW bus, the pair first head to Sugar Ray Leonard's house. Or so they think. Richards, first insisting he's friends with the boxing legend, later admits he doesn't know him, after the two end up knocking on the door of comedian Jay Mohr, instead of Leonard's. Oops.

Seinfeld and Richards talk about old times during the nine seasons of Seinfeld, though the conversation turns a bit sobering when it turns to the infamous racial outburst Richards had on stage seven years ago.

"I busted up after that event seven years ago,” he tells his friend. “It broke me down. It was a selfish response. I took it too personally, and I should have just said, 'yeah, you're absolutely right, I'm not funny. I think I'll go home and work on my material and I'll see you tomorrow night."
