推销员在一个公众会议上大力鼓吹自己的商品:“诸位,这种自动刮脸机好极了.你们只要投入几个硬币,把头支在托架上,电动剃刀就会自动开始刮脸。”听众中一片欣喜,有一人大声问:“每个人的脸型都不一样,剃刀如何处理?”推销员说:“放心,只用剃一次,脸型就都一样了。” The salesman touted his product at a public meeting: “Gentleman, this automatic shaving machine is great.You only have to put in a few coins, put your head on the holder, and the electric razor will automatically shave.” A joy, one of them loudly asked: “Everyone’s face is different, how to deal with the razor?” Salesman said: “Rest assured, only a shave, the face is the same.”
