You knew him as: Husband of friend Monica, roommate of friend Joey and all-around mysteriously employed friend Chandler Bing. Now you know him as: Snarky guy stand-in No. 1 (and Chandler). Perry stretched his acting chops a bit on the critically lauded -- but low-rated -- "Studio 60 on the Sunset Strip" and continued his comedic romp in films including "Serving Sara" and "The Whole Nine Yards." He played the adult version of Zac Efron in "17 Again" in 2009 and tried heading back to the small screen in 2011 as the lead in the short-lived "Mr. Sunshine." He's also been in and out of rehab a few times. Where you'll see him next: Perry is trying his hand at sitcoms again with "Go On," an NBC sitcom where he stars as a Type A sports talk radio host.
