You know what people like reading about? Penises! Half the population has one and the other half wants to get up on one. (Like the mainstream media, I choose to ignore lesbians.) Knowing what a hit these little (or big) guys are, CBS has a rundown of five things you did not know about your penis. Like No. 1: "Your Penis Does Have a Mind of Its Own". In eighth grade Latin, this kid would have the most awkward erections while we waited in the hallway before class to start. Now I know that his sentient penis just enjoyed dead languages. More shockers after the jump!
