Today's David Post post reminds me of two Gentile jokes I heard a while back. They mostly make sense when said by Jews to a Jewish audience, but I figure enough of our readers are either Jewish or Jew-savvy enough.
A Gentile is in a clothing store. "How much for that jacket?," he asks. "$500," the salesman says. "OK, I'll take it," the Gentile says.
A Gentile calls his mother": "Mother, I know I was supposed to be coming for dinner tonight, but this girl I'm interested in is free tonight and I'd like to get together with her instead." "OK, have a nice time!," says the mother.
For those who aren't Jew-savvy enough, the gag is that these are actually jokes about Jews, not about Gentiles.
