There was a knock at the door. When Mary answered it, she found 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.”
Quick as a flash, the young man pushed open the door and barged into the living room.
“Now I know you’re sceptical,” said the salesman, “but just wait till you see what this baby can do!”
With that, he emptied a bucket of dirt, rotten eggs, mushy tomatoes and other trash onto her carpet.
“If this vacuum cleaner does not remove all traces of this garbage from your carpet, Madam, I will personally eat every last bit of it right off your floor.”
“I’ll fetch you a fork,” Mary replied. “I couldn’t afford the bill, so they shut off my electricity.”
