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'm broke and 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 manure onto her hallway
carpet.

''Now, 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 let me get you
a fork, 'cause they cut off my electricity this morning."
