 '30 Rock's' Tina Fey and others on their favorite episodes

From 138 episodes, name a favorite. An impossible task, to be sure, but we had to ask:

Tina Fey (head writer Liz Lemon)

Season 1: "'Tracy Does Conan' because it's when the show really started to find its tone."

Season 2: "'Rosemary's Baby' because I have fond memories of the writers' room for it, and Carrie Fisher was so great" as a guest star.

Season 7: "'Mazel Tov, Dummies' because I'm happy that Liz was able to find love without compromising who she is. And I'm happy Dennis Duffy was at her wedding but not as the groom."

Judah Friedlander (writer Frank Rossitano)

"My favorite was 'Goodbye, My Friend.' I got the chance to do a different kind of acting and break character and show different sides of Frank. It was also my first time working with Patti LuPone (playing my mom), and I had to cut off my sideburns, straighten my hair, pin it back and wear three-piece suits. And there was a 'Harry and the Hendersons' parallel, and I'm a huge Bigfoot fan, so it was amazing on all levels."

Jack McBrayer (NBC page/president Kenneth Parcell)

"One that was particularly important to me was our second episode in Season 1 ("The Aftermath") where we shot on a yacht for an entire day.  We were still getting to know each other and, in hindsight, it was a pretty cool way to be forced to bond with the folks you were going to work with for the next seven years."
