"I give it to them," replied the lawyer, "and then I send them a bill." The doctor was shocked, but agreed to give it a try. The next day, still feeling slightly guilty, the doctor prepared the bills. When he went to place them in his mailbox, he found a bill from the lawyer.
医生和律师正在一个宴会上交谈。他们的谈话常被一些人打断,那些人向医生描述自己的病症,期望获得免费的治疗建议。如此这般一个钟头后,医生有点恼火,于是他问律师:“如果不在办公时间,你是怎么阻止人们向你咨询法律问题的?”
“我会给他们建议,”律师回答,“然后我会给他们寄去帐单”。医生很震惊,但他还是决定这么试一试。第二天,带着点犯罪感,他准备了帐单。当他准备将它们放到邮箱里时,发现了一张来自律师的帐单。
