The only seat available on the train was directly adjacent to a well dressed middle aged French woman and the seat was being used by her dog.
The weary traveler asked, "Ma'am, please move your dog. I need that seat."
The French woman looked down her nose at the American, sniffed and said, You Americans. You are such a rude class of people. Can't you see my little FiFi is using that seat?"
The American walked away, determined to find a place to rest, but after another trip down to the end of the train, found himself again facing the woman with the dog.
Again he asked, "Please, lady. May I sit there?". I'm very tired.
The French woman wrinkled her nose and snorted
"You Americans! Not only are you rude, you are also arrogant....!"
The American didn't say anything else, he leaned over, picked up the dog, tossed it out the window of the train and sat down in the empty seat.
The woman shrieked and railed, and demanded that someone defend her honor and chastise the American.
An English man sitting across the aisle spoke up indignantly
"You know, sir, you Americans do seem to have a penchant for doing the wrong thing.
You eat holding the fork in the wrong hand. You drive your autos on the wrong side of the road. And now, Sir, you've thrown the wrong bitch out the window."
