A dog goes into a butcher's shop with a shopping bag in his mouth....?

in the bag is a note that says '5 lbs of best steak' and �10. The butcher thinks "i'll have him" so he puts some old scraps in the bag. "GRRR!" goes the dog. "Jesus, he's clever" thinks the butcher, so he puts the good stuff in the bag. The dog wags his tail. The butcher tries to short change the dog. "GRRR!" he goes again. so the butcher gives him the right money. The dog wags his tail, opens the door with his paw and trots out. The butcher, amazed, decides to follow him. The dog goes to the traffic lights, presses the on, waits for the traffic to stop and carries on. When he gets home he unlatches the gate with ease and scratches at the door to be in. A man opens the door, shouts at the dog, kicks him up the backside and slams the door. The butcher knocks at the door and says "that is the cleverest dog i have ever seen. He can count, work traffic lights and can tell good meat from bad. And you shout at him. Why?" The man replies "silly git's forgotten his keys 3 times this week!"
