just now while i was studying engineering science,a friend of mine,yong seng suddenly came up with two lame and pathetic jokes.

I) a bird was standing on top of the a sharp object.then suddenly she laid an egg.but why dint the egg break???

II)why did dinosaurs become extinct??


















I)because she wore an underwear so the egg was inside the underwear

II)because ultraman每天杀一只，杀就后就绝种。。。
