Two Irishmen met and one said to the other, "Have ye seen Mulligan lately,
Pat said, "Well, I have and I haven't."
His friend asked, "Shure, and what d'ye mean by that?"
Pat said, "It's like this, y'see...I saw a chap who I thought was Mulligan,
and he saw a chap that he thought was me. And when we got up to one
another...it was neither of us."
