He quickly became a core member of the Brat Pack in the '80s, frequently showing up in films alongside Emilio Estevez, Andrew McCarthy, Judd Nelson and others -- but became a true household name in the late '90s with a recurring role on "The West Wing."

The 2000s treated this star well too -- he acted in tons of made-for-TV miniseries like "Salem's Lot," "Beach Girls" and other projects. Come 2010, he ended up becoming a series regular on "Parks and Recreation," where he played the always-optimistic Chris Traeger.

Now, the guy's hosting a game show called "Mental Samurai," and hanging with his good pal, Chris Pratt, pretty often out in Santa Barbara.
