Michael Richards apologizes for racist rant
Once a beloved sitcom star on Seinfeld, Michael Richards' career went down the drain after going on a bizarre, rageful, racist tangent during a 2006 comedy show. The whole scandal was caught on camera.
Jerry Seinfeld arranged for Richards to appear on The Late Show with David Letterman and offer a public apology, but the audience kept laughing at him, even though Seinfeld begged them to stop. In the end, Richards never recovered, and the segment remains a cringeworthy moment in late-night television.
