Yes, this joke isn't amusing to me either, even when I read it in Chinese. It is perhaps more of a cultural difference than a translation problem. Some humour can transcend these barriers - Mr Bean became famous all over the world - and America's basic, usually more observational humour is often popular abroad. But British surrealist comedy and satire, and comedy which relies heavily on word play, metaphor and other devices isn't going to export so easily. Dark humour (controversial jokes about death, abuse, racism, criminality, religion, etc) is particularly culturally specific too, and also just a matter of personal taste. My dad likes more 60's style humour, whereas younger people like more un-PC humour.

yes, some jokes when we translate it into another language , then it may lose its original taste !

I don't get it ...translation thing probably Do you think these English jokes are funny? What did the fish say when he ran into a concrete wall? Damn Why did the mushroom go to the party? Because he was a Fun-gi (funguy fungi mushroom=fungus) I bet you don't find these funny either ....
