are all girls dumb?

Well I must say that girls aren't dumb, mine would wipe the floor clean with me in any intelligence test as much as she denies it. What I think you are trying to say is are all good looking girls dumb, and no I obviously don't think so and know some very attractive and clever girls. I do however think all women have a crazy or weird streak but its something you live with, they will say the same about us its the gender difference thats all.

Wow great post I bet you still think you make a 'dumb girl' get off as well

There is also a saying that "brawn and brains don't go together" that refers to males. Intelligence is not limited to a certain gender.
