Here's a bit of trivia: the original cartoon of "The Three Little Pigs" by Disney had the Big Bad Wolf pretending to be a Jewish peddler in a rather unflattering caricature.
This bit of the cartoon has been re-dubbed in subsequent releases; the wolf now claims to be working his way through college.
