Pushy salesman

A vacuum cleaner salesman knocks on the door of an old lady’s house. The lady takes one look at him and says, “You are wasting your time, I have no money,” and tries to close the door.
Quick as a flash the salesman jams his foot in the door. He then tips a big pile of horse manure on her carpet and says “If I don’t clean all this up, I’ll eat the rest.”
The old lady says “Fine. But my power was cut off this morning, so let me get you a fork.”
