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. Your 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....Imagine!"

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."
