TMZ:

Did Michael Richards attack the Jews? Two Los Angeles residents have come forward and said that’s exactly what happened last Spring at L.A. comedy club, The Improv.
Carol Oschin and J.P. Fillet say they were at The Improv on April 22 when Richards took the stage. They say that in the middle of Richards’ skit, a man in the audience said something to the comedian, when Richards allegedly launched into an anti-Semitic rant. According to Oschin, Richards screamed at the audience member, “You f***ing Jew. You people are the cause of Jesus dying.”
