英語笑話：無言以對

An aesthetics professor’s grandson asked his grandfather，"grandpa，why did you say that all the false are ugly?”

美學教授的孫子問他爺爺:“爺爺，為什么您說，一切假的都是丑的?”

"That is certainly true. Couldn't you give me an opposite example?”

“那當然了!難道你還能舉出相反的例子來?”

“Oh，yes,"the grandson，climbing in his grandfather’s knee，said proudly，“Looking at yourself，when you put on your false teeth，you look younger and lively; when you get off them,you mouth looks empty and shriveled, which is really ugly Isn’t it an opposite example?”

“能!”孫子爬上爺爺?shù)南ヮ^，得意地說:“您瞧您自己一裝上假牙后又年輕又精神，拿掉假牙，嘴巴又空又癟，那才丑呢!這不是相反的例子嗎?”

The professor could find no answer.
