Sexist joke

A sexist joke is a joke that expresses the sexist belief that one gender or sex is somehow superior to the other.

Examples:

How do you fix a woman's watch?
You don't. There's a clock on the oven!

Why does a man have a hole in the end of his you-know-what?
To get oxygen to his brain!

The perfect woman has got three buttons on her forehead. Labelled: (Kitchen), (Sex), (Off)
