Women don't care if you are funny, they only care about three things: looks, status, and resources.

Here is an interview Norm Macdonald did with Greg Fitzsimmons where he talks about how women perceive guys with a sense of humor. They don't actually care if you are funny. I cherrypicked some of Norm's responses which I believe are 100% spot on. I linked the interview, it is pretty funny, I suggest listening to the whole thing. [Part Norm talks about girls is roughly :40 to 2:50]

Norm: When I was young, they [girls] say they like kids with good senses of humor. I don't know if you got this but I was always funny, but girls would just go, "you're weird". Not funny, weird.

Norm: When I was on SNL, guys would come on and they were handsome guys. They were convinced they were funny. The publicist would come on and say "This is going to be really good for Gabriel's career because he is so funny". And then the fuckin' guy wouldn't be funny at all. And it came to me you know how they always say women like guys with senses of humor, turns out they just laugh at handsome guys.

[Lastly, some pearls of RP wisdom]

Norm: I never did anything for girls. My motive in life was never girls. I hear people buy cars to get girls, tell jokes, or play the guitar but I never had that motive.

TL;DR don't think jokes will get you women, they don't care if you are funny.
