THE LAID BACK LOSER aka THE REAL GUY- Knocked Up
The bearded, bear-like 26-year-old is probably the world's unlikeliest pin-up. True we fell for a few of Rogen incarnations Knocked Up, Freaks and Geeks and Pineapple Express. In fact they are all fairly similar characters with a few different quirks.
Theres something about his inept honesty about himself and inept earnestness and inept...well you get the idea. Also there's something about his realisation that Heigl is soooo out of his league - the opposite of guys who think they're doing you a favour by glancing in your direction.
Or it might just be that even the idea that even when you have a drunken one-night stand with someone, that they'd actually try and make it work long term is kinda sweet.
Also he's funny. Like really funny.
