using a VERY common stereotype jokingly. Some of my ancestors were German Jews and one of my best friends is from a practicing Jewish family. Both of which are meaningless to me but I know some people think you can only make jokes about your own race/religion. Anyways, I tell them to stop being a Jew and they say the same to me when either of us are being cheap about something. It's a joke, get over it. Even if it wasn't, BFD.
