you should watch this video, it is by this Jewish guy named Sacha Baron Cohen. He is a comedian who has all these fake personas (http://www.hbo.com/alig/bios/)
anyway in the video he is Borat Sagdiyev, a journalist from kazakhtstan. He goes into a bar and sings this song called “throw the jews down the well” and all these people are just cheering and clapping along. It is not rehearsed, but filmed live. It is pretty [messed] up.
