You know him as:
Why we like him:
In Season 1, Troy was mostly the clueless love object of Annie's (Alison Brie) desire but now, now Troy is indispensable. And, in our minds, the real hero of "Community." Without him we wouldn't have the bromance that is Troy and Abed, the Twitter account that is Old White Man Says, no one would have saved the zombie day at Halloween and that sneaky very special "drinking is not that great" episode would not have been the same.
Where else you've seen him:
A trio of appearances -- "Young P.A.," "Producer" and "Gay Kid" -- on "30 Rock," which he has also written two episodes (and he was a writer on 25 episodes of "The Daily Show with Jon Stewart").
