A Marine boarded a train on his way home from deployment. The train was quite crowded, and the Marine walked the entire length looking for a seat. There seemed to be one next to a well-dressed middle-aged French woman, but when he got there he saw it was taken by the woman's poodle.
The war-weary Marine asked, "Ma'am, may I have that seat?" The French woman sniffed and said to no one in particular, "Americans are so rude. My little Fifi is using that seat."
The Marine walked the entire train again, but the only seat available was under that dog. "Please, Ma'am. May I sit down? I'm very tired," he asked again. She snorted, "Not only are you Americans rude, you are also arrogant!"
This time the Marine didn't say a word; he just picked up the little dog, tossed it out the train window and sat down. The woman shrieked, "Someone must defend my honor! Put this American in his place!"
An English gentleman sitting nearby spoke up. "Sir, you Americans seem to have a penchant for doing the wrong thing. You hold the fork in the wrong hand. You drive your autos on the wrong side of the road. And now, sir, you seem to have thrown the wrong bitch out the window."
