"NO,"said the man,"They arenn't worth a cent moren than two dollars."
"Well,"Tom said, taking two dollars out of his pocket,"Here's your money.These trousers were hanging outside your shop.The list price of them wad six dollars and a half. But I thought that was too much money, so I wanted to find out how much they were really worth."
Then he walked out of the shop with the pair of trousers and disappeared before the shop owner could think of anything to say.
