Housewife (to delivery boy who has brought a whole load of stuff from the supermarket): “I’m terribly sorry, I don’t seem to have any cash in the house to pay you....could i interest you in some entertainment instead?”
Delivery boy (half an hour later): “Funny --- I could have sworn that blonde hair of yours was real”.
Lady: “Oh, but it is!”
D.B. “Then how come that hair’s black?”
Lady”: “Oh! well, you see, I had to pay the coal man”.
(Note: this is an ancient story which dates me, I’m afraid. I don’t know if coal is still delivered to homes in Britain, the way it used to be. probably not)
