I saw this joke and was quite ashamed of myself for laughing out loud but I've decided to share it anyway! Why do men not get Mad Cow Disease? - Beacause they are all pigs! I apologise right now for the overtly sexist nature of this - boot on the other foot or what?
There's two sexist jokes that made me laugh. One was against men and the other was against women. Sexist against women: "Women are like lava lamps, they're fun to look at but they're not too bright." Sexist against men: "Men are like government bonds, they take forever to mature."
