A priest is walking through a bazaar in a middle eastern town when he is approached by a rather scruffy looking local.
“Dirty postcards?” mumbles the man. “No. Certainly not! Go away.” says the priest.
The man follows him and once again propositions him: “Dirty postcards?” “No. Go away. I told you I’m not interested” says the priest.
The man is undeterred and propositions the priest once more: “Dirty postcards?”
This time the priest looks at the man, glances around him, then reaches into his jacket and produces an envelope. “Ok,” he says, “how many do you want?”
