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 minutes of your time, I would like to
demonstrate the very latest in high-powered vacuum cleaners."
"F*** off!" said the old lady. "I haven't got any money" and she
proceeded to close the door.
Quick as a flash, the young man wedged his foot in the door and pushed
it 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 sh*t all over her hallway carpet.
"If this vacuum cleaner does not remove all traces of this horse sh*t
from your carpet, Madam, I will personally eat the remainder."
"Well," she said, "I hope you've got a f***ing good appetite, because
the electricity was cut off this morning."
