I heard this joke, told by a Jew, as the "boys" (all over 60) played poker at the Elks Club, while I watched. I was about ten. I have heard it many times since. How many times have you heard it?

Two Jews were urinating, standing side by side. One said "Hey, are you from Cincinnati?" Abie answered "Yes, how did you know ?"
The other said, "Well, I've got an uncle in Cincinnati what's a rabbi. He is always cutting on the bias, and you, my friend, are pissing on my feet."
