While I'm generally against people making judgements about other people based on appearance, I think it's fair to judge someone based on how they act. I mean if a guy is acting like an asshole I think it's fair to sign him as an asshole. Afterall, actions speak louder than words.
That picture is frickin' weird. SUre, the guy's weird but everybody has their quirks, right? The chick is just as weird, so I guess they belong together.
