Cleaning

A door-to-door vacuum cleaner salesman knocks calls at a house. When a woman answers
and before she can say anything, he dumps a pile of mud her carpet.
"Lady," he says, “if this cleaner does don't remove all that mud, I'll eat what’s left!"
The woman replies, "Do you want ketchup on that?"
Stunned the salesman asks, "What do you mean?"
“Well,” says the woman, "We’ve just had a power cut."
