I know this is not the same as rape, but an elderly Jewish friend of mine once told me the following story: When she was still young she was once walking with a senior doctor in a hospital who also Jewish. Suddenly he grabbed her ass. Knowing that many Jewish men consider it highly improper to treat a Jewish woman this way and that this man must therefore think she was a gentile, she struggled to recall some words of Hebrew. She managed to come up with a short quote from the Torah, whereupon he instantly let go and seemed totally shocked.

Never heard that one and I've worked with lots of Jewish colleagues.
