A vacuum salesman goes to the first house in his new territory. He knocks, a real tough looking lady opens the door, and before she has a chance to say anything, he runs inside and dumps cow dung all over the carpet.

He says: "Lady, if this vacuum cleaner doesn't clean up that bull shit, I'll eat every bit of it.

That brought a smile to even the tough lady's face, and she asked him: "You want ketchup on that?"

Surprised, the salesman asked: "Why do you ask?"

"We just moved in and the electricity hasn't been turned on yet."
