Is humour/wit unattractive in a woman?

It sort of is, and its because..and I can't really explain it.. men are supposed to be the funny ones and women are supposed to laugh. Humor in men is attractive, and power is too but both of these are not attractive traits for females. Very few if any men would like a women who is more funny and more powerful than them. Female can be funny sure, but its not an attractive trait for them.
