Rarely have I met a woman that had any significant amount of quick witted humor. I dont think its because they arent funny, they just are more reserved with their actions and words I think, they dont just bust out with stuff like MassiveGunz or someone like that.
The only funny females i know are my mother and sister.
When talking to other females its usually me joking and both of us laughing, but they hardly contribute.
one can hardly say females dont have a sense of humour tho. there are some seriously hilarious female comedians.
