A jewish man goes into a public restroom

He goes to the urinal as another man enters and starts using the urinal next to him. The other man looks over at him and asks, "Are you a Jew?"

"Why yes, I am," he replied.

"Are you circumcised?" The second man asked. A bit put off, the first man answered warily.

"A strange question… but yes.. I am circumcised…"

"Did you grow up in New York?" The second man asked.

"Well, yes! I did. How did you know?"

"Did you study under Rabbi Korinski?"

"I did! How do you know so much about me?"

"He cuts at an angle and you're pissing on my shoe."
