I'm looking for a YouTube video I thought was in the sidebar but it might have just been in a post. It was a short sketch board type video discussing the evolution of dating, marriage, and sex. It discussed the effects the birth control had on casual sex and how waiting to get married gives an advantage to men.

Anyways I thought it was a really good video and I can't find it anywhere. I'm hoping some of you know what I'm talking about. Thanks.
