One of the great things about the Internet and the proliferation of camera phones is that where as once you would always be half wondering "was it really THAT bad?" when some celebrity scandal breaks, now you just go to YouTube and wait and see. C.f. the case of Michael Richard, the performer famous as the Kramer from Seinfeld and now as he of the racist tirade. Because the press needs its scandals and would much rather act aghast than analyse, an ambiguous or even satirical remark can easily be trumped as a racist/sexist/homophobic/heterophobic/pressophobic tirade.
In this case it was not like this at all. This was a tirade in the purest sense of the word. It's horrible. The abuse is way over the top for people allegedly talking during your show, which is annoying, but can be dealt with better and is usually a sign that your act is not going well. In fact in the videos which only start during the tirade, he doesn't look like a man whose act is going well. However there is ONE funny thing said on the videos. It's by one of the guys walking out: "That's why you're a reject, never had no shows, never had no movies: "Seinfeld" that's it!"
