A Jewish Joke

A man was standing having a pee in the toilets when he turned to the man next to him and said

"You're Jewish aren't you ?"

and his neighbour replied, " Yes, I am."
and the man carried on " And you're circumsized aren't you ? "

and his neighbour replied "Yes, I am it's part of my faith"
and the man carried on " And it was the old Rabbi Stein who did the circumcision"

And his neighbour said "That's amazing. That's right. How could you possibly know that?"

And the man said, "Well, the old Rabbi was cross-eyed, he always cut sideways and you're pi55ing on my foot !"
