I've heard one or two stories from Cooper's fans meeting him and him coming off as uninterested or full of himself. Granted it could be a coincidence that they met him on an off day. Also possible, or likely, he's a douche that just plays himself in most roles. Can't say I'm honestly that fond of him myself outside of the hangover. And even there he's a douche. It's just funny in that context. Kinda reminds me of my hatred of Katherine Heigle just from seeing her in Knocked Up and then hearing rumors that's she's just that way. Who knows how true it is. But it is interesting and mildly vindicating
