There is gender bashing, and there is wry humor. Two examples:

Why did the cave men drag the women by their hair?
Because if they dragged them by their feet, they would fill up with dirt.
Now, that, and any other "joke" about women's genitalia are offensive. I think that men who think that's funny, and can't wait to repeat it, have an issue with being able to relate to women. It's 8th grade hunor.

Why are Dolly Parton's feet so small?
Because nothing grows in the shade.
To me, this is clever, but not especially offensive.

A guy comes home after being on a week long drunk.
His wife, furious, said "Where the hell have you been"?
"On a drunk, why"?
She said, "How would you like it if you didn't see me for a week,"?
He said "I'd love it"!

About a week later, he could see her a little bit out of the corner of one eye.
