Two Englishmen were waiting in Heathrow Airport.
"I say! Isn't that the Archbishop of Canterbury over there?"
"Nothing like him."
"I'm sure of it."
"Have it your way. Go and ask him."
. . .
"Well, how did it turn out?"
"He was noncommital."
"Noncommital? How so?"
"I asked him if he was the Archbishop of Canterbury, and he told me to fuck off."
