2. ELLIE KEMPER

Kemper plays the naive Dundler Mifflin receptionist, Erin, who still seems endearing when she hides in her hair and claims that was her bedroom in her foster home days. Um, OK? Trained in theater and improv, Kemper became a hit after only four episodes and was signed on as a regular cast member of The Office. Before appearing weekly on network TV, you may remember her as "Blowjob Girl" on College Humor, though we're pretty sure she'd much rather be recognized for playing Erin. As long as we get to see this cute redhead on screen, we're cool with whatever.
