A peddler knocked at the door of a housewife.
"I sell all kinds of things for the house. Do you want to buy something?"
"No, I don't want anything," said the housewife firmly.
"Maybe a pan or a pot?"
"No, I don't want anything. Now, get going. I don't want anything."
"Maybe a clothes brush?"
"No, I don't want anything!"
"Maybe a vacuum cleaner?"
"I don't want anything. Get going!"
"Maybe a tablecloth? Some hairpins? I've got all kinds of things."
"Now, listen to me. If you don't get going, I'll whistle for a policeman."
"Do you want to buy a whistle?"
