A Vacuum salesman knocks on an old lady's door and says "I have the best vacuum money can buy and I'm here to sell it to you." The old lady bluntly says "I have no money to buy anything,you're wasting your time." The salesman reluctantly says "My vacuum is the best,Im going to dump this whole bag of dog shit on your Welcome Mat and if my vacuum can't suck every last crumb up,I'll eat the pile myself." The old lady walks to the kitchen,finds a fork and gladly hands it to the salesman."I won't be needing that at all!" He exclames. The old lady replies "Yes you will,they shut my power off this morning."
