If you missed Michael Richards' appearance on Letterman's show last night after his racist tirade at a comedy club in West Hollywood, CBS' Late Show Web site has the video, which you can see here.

Setting aside Richards' racial slurs aside for a moment, watching the video of his onstage meltdown made me think of the kind of heated exchanges people get into where one becomes so enraged they reach deep into their reserves for the ultimate atomic bomb of an insult, the one word or phrase they can say that will completely flatten the person who is attacking them, and in Richard's case his racist comments . During his appearance on Letterman's show, Richards acknowledged that he lost his temper, and it seems fairly obvious to me that whatever self-censoring mechanism he had was overrode by his need to take down the people who were heckling him.
