Housewife     :  “I’ve told you. I don’t want a dictionary, I already have one.”

Salesman      :  “But I don’t see it anywhere in your bookshelf.”

Housewife     :  “It’s there on the table.”

Salesman      :  “Oh, lady, you can’t  fool me. It’s the Bible.”

Housewife  (with astonishment) : “How do you say so !”

Salesman      :  “By the dust on it.”
