A Good Polish Joke

Guy walks into a bar, orders a beer and asks the bartender if he wants to hear a good Polish joke. The bartender says, "Hey buddy, I’m Polish. And see those two big guys over there? They’re Polish. And those two policemen eating lunch? They're Polish, too. Now, wise guy, you still want to tell your joke?"

The guy says, "Heck no, not if I have to tell it five times!"
