    Mr. and Mrs. Smith have just opened a small restaurant. In order to attract customers, they put a notice in front of the restaurant, which said: “Meals on the house for three days.”

A foreign student who didn’t know much English passed by the restaurant on the second day. It was lunch time, and he felt hungry. “Well, here is a restaurant. I’m going to have something to eat,” he said.

He saw the notice when he walked towards the restaurant. “American people are really strange. They even eat dinners on the house! But how can I get onto the top of the house?” he asked himself.

He looked around and found a ladder against a tree nearby. He was very glad. But as he reached the top, he heard someone shouting at him: “Hey, what are you doing up there?” Mr. Smith was looking at him angrily. Beside him was a policeman.

“Your notice says ‘Meals on the house for three days’. Is it just a joke?” the foreign student answered.
