3. Aziz Ansari
As he hustled his way through the New York City stand-up comedy scene, Ansari also performed sketch and improv comedy at the Upright Citizens Brigade. His career took off after he formed Human Giant with Rob Huebel, Paul Scheer, and Jason Woliner. Shortly after Human Giant wrapped its two season run on MTV, Ansari was on his way to becoming a household name.
2009 brought increased stand-up success and prominent rolls in the films Funny People, Observe and Report, and I Love You, Man. While we see Ansari most often on Parks and Recreation these days, he's involved in a number of exciting comic projects.
