I heard this great Polish joke!

Guy walks into a bar, sits down and tells the bartender “I heard this great Polish joke!”

 

The bartender cuts him off. “Listen, buddy,” he says sternly. “I’m Polish. See that big guy at the end of the bar? He’s Polish. And that even bigger guy sitting over there? He’s Polish too. Now, do you still want to tell that joke?”

The guy thinks it over. “Nah. I don’t want to have to explain it three times”.
