A door-to-door vacuum salesman goes to the first house in his new territory. He knocks, a lady opens the door, and before she has a chance to say anything, he runs inside and dumps horseshit all over the carpet. He says, "Madam, just to show you how confident I am in the quality of my vacuum, I'll eat whatever the vacuum doesn't pick up." The woman smiles and asks, "Could I get you some ketchup with that?" The salesman scoffs confidently and says, "I assure you my vacuum has more power than any other on the market today!" The woman replies, "Well, that may be so, but we just moved in and the electricity isn't turned on yet."
