... A dog walks into a butchers shop, spends a number of minutes looking at the meat on display, and eventually indicates with a nod of his head and a bark that he would like some lamb chops. The butcher, thinking the dog would know no better, starts to wrap the worst lamb chops in the shop. The dog barks furiously and continues to bark until the butcher selects the finest chops from the display counter. The butcher weighs the meat and asks the dog for £5.90. Again, the dog barks furiously until the butcher reduces the bill to the correct price of £3.60. The dog hands over a five pound note and the butcher gives him 40p in change. Once again, the dog barks continuously until the butcher tenders the correct change. The dog then picks up his package and leaves the shop. Now the butcher is extremely impressed and decides that he would like to own this clever pooch so he shuts up shop and follows the dog. After ten minutes or so, the dog climbs the steps to an old Victorian terraced house. When he gets to the top, he shakes his head as though in frustration, gently places the package of meat on the floor and, standing on his hind legs, rings the doorbell. Presently, a man opens the door and proceeds to shout and threaten the dog. The horrified butcher leaps up the steps and begs the man to stop saying that he was shouting at an extremely intelligent dog. He then went on to explain how the dog had procured the best lamb chops in the shop, insisted on paying the advertised price and quibbled over incorrect change! The man looked at the butcher and said:
"Intelligent he may be, but this is the third time this week he's forgotten his keys".
