A vacumm cleaner salesman knocked on an elderly lady's door hoping to sell his newly found product...She opened the door, and says, "Go away, I have no money for that." He sticks his foot in the door, and says, Don't be so hasty Mam." This is the new state of the art for cleaning.......He dumps a bucket of horse manure on her carpet, and told her if this newly developed vacumm cleaner doesn't clean up all the manure off your carpet, I will eat the remains....."She says, let me go get a spoon, because my electricity has been shut off."
