Kramer's Racist Outburst

About two weeks ago, one of the most beloved and hilarious TV characters shocked the world with his repetitive use of the N word during a stand up comedy skit. Michael Richards has been recovering from his rage disorder for some time. Then in November when he was teased by a African American individuals in his audience at Laugh factory, he retaliated with racist comments which astounded even himself. I have included the clip below. I would love to hear you comments on this incident.
FYI: several curse words are said in this video clip.
