Funniest Role: Casey Klein on Party Down
Memorable Quote: “If I had a glass eye, I'd always do that-pop it out and put it in my mouth. Throw it at people. Why not?”

Caplan is the definition of a funny girl today. Her sassily sarcastic tone is beyond comparison and you probably didn't even realize it was her. She's been in cult comedy hits like Freaks and Geeks and Party Down as well the Sundance hit, Bachelorette. Not to mention, she, folks, is the meanest goth you had an uncontrollable crush on: Janis Ian from Mean Girls.
