An enthusiastic door-to-door vacuum salesman goes to the first house in his new territory. He knocks on the door and a real mean and tough looking lady opens the door, before she has a chance to say anything, he runs inside and dumps cow shit all over the carpet. He says, "Madam, This is the best vacuum cleaner in the world. If this vacuum cleaner doesn't do wonders cleaning all this shit up I'll eat every last chunk of it." She turns to him with a smirk and says, "Would you like ketchup with that?" The salesman says, "Why do you ask?" She says, "We just moved in and we haven't got the electricity turned on yet."
