Before Lizzie Caplan was a wannabe actress working as a waitress for Party Down, she was a high school student trying to make sure the party got the keg in Freaks & Geeks. She looks exactly the same now as she did when she was 17 in that 1999 episode but her hair is longer. UPDATE: LaQuonda pointed out to me that Lizzy Caplan went to high school with one of her co-workers on Party Down, Martin Starr was also 17 when he played the tallest Geek on the show in 1999.
xoxo LaQuonda for your good eye on that! I was actually wondering what happened to that actor because he had such a nerdy look and you saved me from the IMDB search!
