It is really a funny joke
Tom lived by himself a long way from town. He hardly went to town. But next month was the birthday of his little sister. His little sister hoped to have an omega replica watch all the time. To help his little sister to complete his dream, he decided to went to town and bought one fro her. He got out and reached that luxury replica watches shop in the town.
After he bought it, he went into a restaurant and sat down at a table. When he looked around, he saw some old people put glasses on before reading their newspapers. So after lunch he decided to go to a shop to buy one pair, too. He walked along the road, and soon found a shop beside a Movado replica watches stand.
The man in the shop let him try on a lot of glasses, but Tom always said, “No, I can’t read with these.”
The man became puzzled, and he said, “Excuse me, but can you read?”
“No, of course I can’t!” Tom said angrily. “If I could read before, do you think I would come here to buy your glasses?”
