A little old lady answered a knock on the door one day, only to be
confronted by a well-dressed young man carrying a vacuum cleaner. "Good
morning," said the young man. "If I could take a couple of minutes of
your time, I would like to demonstrate the very latest in high-powered
vacuum cleaners." "Go away!" said the old lady. "I haven't got any
money!", "I'm broke!" and she proceeded to close the door.
Quick as a flash, the young man wedged his foot in the door and pushed
wide open. "Don't be too hasty!" he said. "Not until you have at least
seen my demonstration." And with that, he emptied a bucket of horse
manure on to her hallway carpet. "If this vacuum cleaner does not remove
all traces of this horse manure from your carpet, Madam, I will
personally eat the remainder." The old lady stepped back and said,
"Well, I hope you've got a damned good appetite, because they cut off my
electricity this morning."
