John Scurti, 'Rescue Me'
"Rescue Me," FX
You know him as: The nun-dating, financially unstable Kenny "Lou" Shea of 62 Truck
Why we like him: "Rescue Me" took a couple of weird, controversial turns this past season, and in the process alienated some of its fans. Scurti, however, was (as he's always been) the show's most reliable source of comedy, and he's just as good at playing the dramatic moments.
Where else you've seen him: He was in "War of the Worlds" and in "Rescue Me" mate Denis Leary's cult classic "The Ref."
