Myra Rhodes, an elderly lady, answered a knock on the door one day, to be confronted by a well-dressed young man carrying a vacuum cleaner.

Good morning, Maam, 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.

Go away! said Myra brusquely. Im broke and havent 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. Dont be too hasty, he commanded. 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.

Myra stepped back and said with a smile, Well let me get you a spoon, young man because they cut off my electricity this morning.
