A man who's from a country with no religion saw a priest walking down the street. Noticing his collar, he stopped him and said "Excuse me, but why are you wearing your shirt backward?"
The priest smiled benevolently, "Because, my son, I am a Father."
The man scrathed his head. "But I am a father too, and I don't wear my shirt backward"
Again the priest laughed, "But I am a Father of thousands."
To which the man replied, "Well, then, you should wear your shorts backward!"
