A Polak saw a priest walking down the street. Noticing his collar, he stopped the priest and said,
"Excuse me, but why are you wearing your shirt backwards?"
The priest laughed, "Because, my son, I am a Father!"
The Polak scratched his head. "But I am a father too, and I don't wear my shirt backwards!" Again the priest laughed. "But I am a Father of thousands!"
To which the Polak replied, "Well then, you should wear your shorts backwards"
