The American sense of humor is generally more slapstick than that of Britain. I think this arises from a cultural difference between the two. American jokes are more obvious and forward, a bit like Americans themselves. British jokes, on the other hand, tend to be more settled, but with a dark or sarcastic undertone. There is usually a hidden meaning. This may stem from the fact that British culture is more reserved than American culture.
