英译中：这个英语小笑话是什么中文意思?
John walked into a store which had a sign outside:“Second-hand clothes bought and sold.”He was carrying an old pair of trousers.He asked the owner of the store,“How much will you give
me for these?”The man looked at them and then said rudely,“Five dollars.”“What!”said John.“I had guessed they were worth at least ten.”“No,” said the man, “they aren’t worth a penny more than five dollars.”“Are you sure?”asked John.“Very sure,”said the man.“Well,”said John, taking five dollars out of his pocket, “Here’s your money.These trousers were hanging outside your store.The price tag on them said $12.50.Yet,I thought that was too much money.So I wanted to make sure how much they were really worth.”Then he walked out of the store with the pair of trousers.He disappeared before the surprised store owner could think of anything to say.

答案

John走进一个商店,那个商店在门口挂着牌子“二手衣服买卖”,他带了一个旧裤子进去,问那个店主：“这个裤子你可以给我多少钱?”
那个店主看着他然后粗鲁的说：“5美元”,“什么?”john问,“我认为他们至少值10美元”,“不”那个男的说,“他们不可能多过5美元”“你可以确定么?”John问,“非常确定”店主答道,“好吧”John从自己的兜里掏出5美元,“这是你的钱了,这些裤子本来就是挂在你的门口的,他上面写着12.5美元,我认为他们太贵了,所以我想知道他们到底值多少钱,”然后他走出去拿着那些裤子,他在那个店主想怎么说的时候已经走远了.
