A little old lady answered a knock on the door one day, only to be confronted by Banta, carrying a vacuum cleaner.
"Good morning", said Banta. "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!"
And she proceeded to close the door. Quick as a flash, Banta 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.
"If this vacuum cleaner does not remove all traces of this horse manure from your carpet, Madam, I will personally eat the remainder."
"Well," she said, "I hope you've got a damned good appetite, because the electricity was cut off this morning."
