A German tourist walks into a McDonald's in New York City and orders a beer. The local guy in the line behind him immediately gives him a verbal jab, "They don't serve beer here, you moron!"

The German fellow felt embarrassed, however he turned to the New Yorker with a surprised look on his face and begins to chuckle.

"And what's so funny?" the New Yorker demands.

"Oh, nothing really, I just realized how stupid you are. You
came here for the food!"
