Two men are standing at the urinal, doing their business, when one starts to strike up a conversation.
"Excuse me, sir, do you happen to be Jewish?"
"Yes, indeed I am."
"And do you happen to be from Krakow?"
"Yes, how do you know?"
"And you always went to the little synagogue in the Pitliwsky road?
"Yes, do we know each other?"
"No, but Rabbi Goldberg was responsible for the
Bris there, and he was infamous for not being able to make a straight cut."
"What does that have to do with anything?"
"You're peeing on my shoes."
