A dog goes into a grocer’s with a basket in its mouth. In the basket is a shopping list and a purse. The grocer reads the list, puts the goods requested into the basket, takes some money from the purse and puts back the change. The dog runs off home.
This happens every week for months and the grocer becomes extremely impressed by the animal’s intelligence and its dedication to its task. One day he decides to follow the animal home and see if its owner would be willing to sell it. The dog eventually leads the grocer to a run-down house where it puts the basket on the doorstep and rings the door-bell with its nose.
After a few seconds an old woman opens the door and starts hitting the dog with a stick.
‘Stop!’ shouts the grocer. ‘What are you doing? That’s the most intelligent dog I’ve ever seen in my life.’
‘Intelligent?’ shouts the old woman. ‘That’s the third time this week he’s forgotten his keys.’
