Why Women Aren't Funny

About a year ago, I read an article that discussed the different ways that men and women processed humor. When men were told a joke, their levels of pleasure were pretty steady throughout the telling, even before a punchline. Women, however, are usually more skeptical of jokes and so when a joke was funny, their pleasure spiked at the punchline, meaning that they actually enjoyed it more, but in a sudden burst of pleasure. For me, that explains why women can't remember jokes -- we automatically assume it won't be funny, thus there's no need to commit it to memory.
So that's the justification that I give as to why I can't tell anything other than knock-knock jokes or elephant jokes.

Of course, there are fantastic women comedians out there... but the field is dominated by the fellas. Vanity Fair seeks to unravel why women aren't considered to be funny.

Why are men, taken on average and as a whole, funnier than women? Well, for one thing, they had damn well better be. The chief task in life that a man has to perform is that of impressing the opposite sex, and Mother Nature (as we laughingly call her) is not so kind to men. In fact, she equips many fellows with very little armament for the struggle. An average man has just one, outside chance: he had better be able to make the lady laugh.
