There are five men and a single woman all dangling from a rope, waiting for someone to rescue them. Unfortunately the rope starts to fray and they all decide that someone has to sacrifice themselves to save the others. After some time discussing who should sacrifice themselves, the woman says that as women are used to sacrificing themselves and that men are the better sex, she will sacrifice herself. The men all applaud her, and an hour later the woman is rescued.
Mildly humorous ?
Now try it the other way around :-

Still funny ?
It sometimes seems that it is far more acceptable for men to be portrayed as stupid in jokes than women. Is this fair ? If it is wrong to portray women as stupid in jokes, it is wrong to portray men as stupid too; similarly if it is funny to read about stupid men, then it is funny to read about stupid women.
