-An old couple go into a cafe for a cup of tea. They sit down, make an order. Then they see a chimpanzee walks in. It looks rather strange: the chimpanzee is wearing a suit and carrying a newspaper. The chimpanzee sits down and orders a cup of tea and a cheese sandwich. The chimpanzee finishes his tea and sandwich, pays and walks out. The old couple is astonished, they go to a waiter and the woman says, 'I've never seen anything like that before!' . The waiter replies,'Yes, very strange.He normally has a salad sandwich.'
