This week's Onion has a feature story on the previously mentioned comedy troupe, Stella.
O: Why do you think there are so many Jews in comedy?
MIB: Because big noses are funny.
DW: Also, a lot of Jews have sort of thin, spindly fingers they use to take money out of cash registers. That's very funny.
MS: If you prick them, do they not bleed?
MIB: The answer is no, they don't. They ooze. They ooze dirt.
