Q: Is it because men are able to laugh at things that women can't? Like abortion?
A: You are half right. The percentage of male comedians to female comedians is far greater. It's not sexist, it is simply the nature of things. Men have developed a sense of humour because they realize that it is attractive to women. An ugly bloke who can make a woman laugh, is in with half a chance. Consequently men actually work on being funny, not all can do it, but many do and the men do it in greater numbers than women
