You know Katherine Heigl, the mouthy one from Knocked Up and Grey's Anatomy? You want her to be your girlfriend. You do.

You want Katherine Heigl to be your girlfriend because an AskMen.com survey has declared that Katherine Heigl is the most desirable woman on the planet and, as a man, it's the law to want her all to yourself.

And, you know, even if you're not a man you probably want Katherine Heigl to be your girlfriend as well. We're open-minded people, so we understand if you girls want a piece of Katherine Heigl too. Our only request is, if that should ever happen, that you film it and send us a copy. For research purposes. There's nothing funny about it.
