If you've ever seen an episode of the hilarious Flight of the Conchords, you'll recognize Kristen Schaal. She played the hysterical lone fan / stalker of the band and every single time she was on the screen she stole the show.
I ran into her leaving the Emmy awards and she was kind enough to stop for a picture. Hooray! Love that show. Now, if only I can get the other guys! Fingers crossed. Someday.
