Call me sexist, but there has never been a funny woman stand up comedian.
Do you really think that there's no such thing as a funny female stand up comic?
Well, I've never seen any funny female comedians in my life.
Generalizing women based on their gender is dangerous and can be very upsetting to them. If people hear you talk like that they will think you are sexist and not want to talk to you. You should try to be more open minded and realize that women can be just as funny as men.
