I've read about this and agree with an interesting theory,
Men are already attracted to Women, therefore Women don't really need to make a Man laugh or charm him in particular. It usually works the other way. Peacocks for example.. the male is brightly coloured and will show his plummage. The femail doesn't need to. He already favours her.
That said, I do like funny Women. Sense of humour, as in an actual sense for funny things doesn't necessarily mean cracking the funnies all the time it can just be a subtle appreciation of wit or something that appears genuinely funny?
