There is something special about the sitcom 30 Rock. Created by Tina Fey and airing for seven seasons from 2006 until 2013, the show followed the lives of Liz Lemon and her coworkers at a sketch comedy TV show called TGS with Tracy Jordan. Fans still watch the show to this day thanks to its quirky storylines, quick-witted humor, and fast pace. It wasn't a typical sitcom with a cheesy laugh track and Liz wanted more than just to fall in love and get married (although, sure, she wouldn't mind that at all).

A TV show is only as great as its characters, and luckily, the 30 Rock characters are truly impressive. They're all super strange... but in an incredible way. Here are the MBTI of the characters on 30 Rock.

 Kenneth Parcell: ISFP

Jack McBrayer's 30 Rock character, Kenneth, is a page who gives tours around the TV studio. He's never seen with a frown on his face and seems like he's way too sweet and innocent to really know what's going on. Of course, that's the truth: he comes from a small town in the South and is pretty freaked out by the big city.

Since Kenneth's job is to help other people and keep things running smoothly, his MBTI would have to be ISFP or "Versatile Supporter." It's interesting how well this works with Kenneth's personality: as the official description says, "People with ISFP preferences enjoy providing practical help or service to others, as well as holding firm to their values when bringing people together and facilitating and encouraging cooperation." Kenneth is often torn between the strange beliefs he has from his background and becoming a part of the team at this NYC TV studio.

 Cerie Xerox: ESFP

Katrina Bowden plays Cerie, the assistant on the sketch comedy show. She's shown as a huge ditz who never wears enough to work, and Liz is constantly worried about the fact that Cerie isn't dressed in what most people would wear to work.

Cerie would definitely be an ESFP or "Enthusiastic Improvisor." This personality type is extremely social and prefers to be with other people, which is exactly what Cerie is like. She's often seen chatting with the staff on the show and seems like she would rather hang out or go to a party than do her job. ESFPs are described as "playful" and "sociable" and "outgoing." Cerie is never outwardly mean to anyone, but she does tend to insult Liz sometimes because to Cerie, if someone isn't as young as she is, they're already way too old.

Drew Baird: ISTJ

Jon Hamm plays Liz Lemon's love interest, Drew Baird. He lives in her building and he's a pediatrician, so coupled with his good looks, he seems like the perfect man. Liz is super into him for those reasons... but it soon becomes clear that people let him get away with anything and everything because he's so attractive.

Drew's MBTI is ISTJ or "Responsible Realist" because he's realistic about the way that others look at him. He's honestly not that intelligent, but the truth is that he's totally okay with things being the way that they are. He wants to live in his bubble where everyone loves him. ISTJS are said to not love change, and Drew definitely doesn't want anything about his situation to change.

Jonathan: ISTP

Most of the time, the boss on a sitcom has an assistant who has some quirks and sets up meetings or answers the phone. Jonathan is Jack Donaghy's assistant, played by Maulik Pancholy. He's a fairly typical sitcom assistant character as he brings a lot of humor to whatever scene he's in. He's not super quirky, but he's still an important part of the show.

Jonathan's main personality trait is that he has a big crush on Jack, so he'll do literally anything for him. He's an ISTP or "Logical Pragmatist." He's got all the good traits that an assistant has, from being someone who will "respond quickly" to someone who is "self determined."

 Jenna Maroney: ESFP

Jane Krakowski's 30 Rock character, Jenna, is hilarious, obsessed with herself, and totally unaware of how others see her. Her shining moment is when she stars in the movie The Rural Juror and no one can figure out how to pronounce the name of it. She definitely thinks that her role on TGS is more impressive than it actually is, which is part of the joke. But she's a good friend to Liz and a sweet person at her core when all is said and done.

Her MBTI is ESTP or "Enthusiastic Improviser." Like Cerie, Jenna likes to be social, and she also likes being the center of attention. She's "optimistic" and "resourceful." She doesn't like when other people say that her ideas are bad or don't listen to her. She honestly just wants to be taken seriously (and some praise wouldn't hurt, either).

Tracy Jordan: ESTJ

Tracy Morgan plays Tracy Jordan, the offbeat star of TGS. Liz is pressured to hire him and made him the focus and star of the show, and while there are many stressful moments because Tracy is so out there, it does seem to work out in its own weird and wonderful way.

You never know what you're going to get with Tracy. He's unpredictable and he's not exactly someone with an amazing work ethic. He pretty much does what he wants and has some very strange logic. Tracy's MBTI is ESTJ or "Efficient Organizer." He has a team behind him at all times and really likes it that way. When he wants something, he asks people to get it for him. As the description says, "People with ESTJ preferences drive themselves to reach their goal, organizing people and resources in order to achieve it. They often have an extensive network of contacts and are willing to make tough decisions when necessary."

 Jack Donaghy: ESTP

Alec Baldwin's 30 Rock character Jack is beloved because he's your typical boss who cares about money and seems pretty greedy, but he's got a soft spot for Liz, even if he would never admit it.

Jack's an ESTP or "Energetic Problem-Solver." He often seems like he's just had about ten cups of coffee and like he could be up for days, working and making deals. ESTPs don't like "goals not resulting from efforts" or when they have "commitments." Jack is a funny guy because it seems like he wants to be in a serious relationship in some episodes because he falls fast and hard, but at other times, he's pretty happy-go-lucky.

Liz Lemon: INFJ

Liz Lemon is an INFJ or "Insightful Visionary." She's the main writer on TGS and works so hard, it's inspiring. As the official description says, "They are typically idealistic as well as imaginative and visionary. They are also sensitive and reserved." That's totally Liz: she's kind, funny, smart, and knows when something is and isn't worth her time.

Liz just wants to be happy in both her work and personal life. She wants to find a nice guy but she's also very interested in doing well at her job. INFJs don't like when they can't focus on their regular routine, which describes Liz. She loves going to work (and eating the foods that are part of her work day, too). Liz is a dream of a character and although everyone on 30 Rock is great, Liz is really the heart of it.
