A little old couple walked slowly into McDonald’s one cold winter evening. They took a table near the back wall, and then the little old man walked to the cash register (收銀臺) to order. After a short while he got the food back and they began to unwrap it.

There was one hamburger, one order of French fries and one drink. The little old man carefully cut the hamburger in half and divided the French fries in two piles. Then he neatly placed the half of the food in front of his wife.

He took a sip (啜) of the drink and his wife took a sip. “What a poor old couple!” The crowd thought.

As the man began to eat his hamburger and his French fries, his wife sat there watching him and took turns to drink. A young man came over　　　　 . He offered to buy another meal for them. But they refused politely and said that they got used to sharing everything.

Then a young lady asked a question of the little old lady. “Madam, why aren’t you eating? You said that you share everything. What is it that you are waiting for? ”

“The teeth, ” she answered.
