Well, it's about time someone exposed those loser chimps for what they really are. Oh, the girls aren't so bad. I have several chimp girlfriends and we get along just fine. It's the guys. You see, girl chimps, unlike you humans and us bonobos, go into heat and that's the only time they'll let the guys have anything to do with them. That makes for some seriously frustrated guy chimps. And since chimp sex is all about reproduction those guys get really nasty trying to make sure it's their DNA that gets replicated.

Now, we bonobos invented what you humans call "sport fucking". We are the original "make love, not war" crowd. You don't see guy bonobos worrying about passing their DNA on. They know it's going to happen 'cause you can't have sex eight or ten times a day without someone eventually getting knocked up and, if you're a guy, eventually it's going to be you that does the knocking.
