Three Englishmen were in a bar

 

the Englishman went back to his buddies. "You are right, he is unshakable!"


"No, no, no," the third Englishman chimed in. "I know just how to bug him, you just watch."


The Englishman walked over to the Irishman, tapped him on the shoulder and said: "I hear your St. Patrick was an Englishman!"


The Irishman replies, "Yeah, I think that’s what your buddies were trying to tell me."
