性促狭，喜欢捉弄人。

师爷爷从英国来，老板请客，与师爷爷同桌，席间讲到电影，遂想起大腕中葛大爷的三楼楼长的故事，讲与众同门，一小女生误入陷阱，遂满桌哄笑，唯师爷爷不懂中文，不知所笑何事，“What？”

众同门鼓动我讲给师爷爷听，于是用蹩脚英语讲：As there are not enough nurses in the psychiatric hospital,they decided to select several patients with less congnition impairment to administrate daily affairs. The chief went to the first floor, took out an apple and ask,what is this? A patient shouted,apple! yeah, you are the chosen one. Then, he came to 2nd floor,took out a banana and asked,what is it? Another patient shouted,Banana!! O.K. You are selected.Then at the 3rd floor, he took out this(我指着我的手机，装作不知道怎么用英语表述)“So,how should we call it in English?”.师爷爷说Cellphone.同门大笑，说Congratulations! U are the chosen one.师爷爷恍然大悟，很无奈的说，That is very funny.
