Are Men Funnier Than Women?

No, but we think they are:

While the subjects rated men's and women's [humorous] caption-writing abilities roughly equally in a gender-blind test, they were so devoted to the stereotype of women being less funny that the subjects misinterpreted their own rankings. … Most women who have a sense of humor can tell you about a time they've told a joke, had it blatantly ignored by their friends and family, and then heard a man tell the same joke (having subconsciously stolen it from the ignored woman) to peals of laughter.
