Fairly attractive actress best known for her role on the OC. The only other place I've seen her was in The Sixth Sense. She's the dead girl that got killed by her mother. Word is she has an eating disorder, and ironically, her first appearance in The Sixth Sense shows her scaring the crap out of Cole Sear due to the green stuff pouring from her mouth.
I was watching The Sixth Sense and my buddy was like, "Dude, that's Mischa Barton! Wait, is it? Yeah!" Then I said, "Yeah, she's on The O.C.! Sweet!"

Ugly.
(extended because UD needs to have at least 3 words: Mischa Barton is pale, skinny and lacks any real sex appeal to any form of life with a spinal column. Probably attractive to moluscs though.)
"Argh, I just saw Mischa Barton on The OC." "Quick, to the bathroom, we have eye-soap."

An ugly, non talent girl, who looks like a forty year old woman, and sounds like a man.
"Wow, that forty two year old smoking waste looks and sounds like Mischa Barton!"
