Mr. and Mrs. Smith have just opened a small restaurant. They want people to come to the restaurant to eat, so they put a sign in front of it, 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 lunchtime and he felt hungry. "Well, here is a restaurant. I'm going to have something to eat," he said.
He saw the sign when he walked towards the restaurant. "American people are really strange. They even eat on the house!  But how can I get onto the top of the house?" he asked himself
He looked around and found a ladder(梯子)against a tree nearby. He was very pleased. But as he got up to 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.
“Doesn't your sign say 'Meals on the house for three days'? Is it just a joke?" the foreign student answered.
On hearing this, both Mr Smith and the policeman laughed. "Do you know what '60n the house" means? Look it up in your dictionary."
