Man vs. Woman
I can't help wondering what it is that make Men and Women think in different ways. It often leads to misunderstanding and frustration, and a lot of generalisation such as "Men/Women are always like that" usually expressed by women/men respectively.
The funny thing is, I know more than half a dozen women that I do not understand, and I know for certain two men which I do not grasp. This small statistic shows that it is not always the case that you can understand the ways of the people of your own gender.
When in doubt, I go to the Uncyclopedia to clarify things.
