Where You've Seen Them Before: In addition to her career-making role as Annie's Boobs on "Community," Crystal also co-starred in "We Bought a Zoo" as part of the zoo that was bought by we.

Breakout Role: Dr. Rizzo, an ambulance-driving part of the veterinary team on NBC's "Animal Practice."

Why: Justin Kirk and JoAnna Garcia-Swisher are the stars and supporting players like Tyler Labine and Bobby Lee may be familiar faces, but the pilot for "Animal Practice" indicates that the producers know that when a scene needs a capper, cutting to Crystal never fails. And NBC isn't unaware that the simian is the  network's newest star, using Crystal for multiple exposure opportunities at the Television Critics Association press tour.
