A woman was shopping in her local Asda, where she selected 4 pints of semi-skimmed milk, a box of six eggs, a carton of orange juice, a romaine lettuce, a jar of Nescafe and 2 packs of bacon.
While she unloaded the items on the belt at the check out, a drunk standing behind her was watching intently as she placed each item down. Then, as the cashier was ringing up the purchases, he said to her "You must be single."
The woman was surprised by this, but somewhat intrigued by the accuracy of the drunk's statement, since she was indeed single. She looked again at her six items on the belt and saw nothing unusual about her selections that might indicate her marital status. So curiosity got the better of her and she said, "Well, you're absolutely correct, but how on earth did you know that?"
The drunk replied, "Because you're ugly."
