Molly Shannon didn't just join Saturday Night Live in 1995. She basically saved it. People forget how rough the mid-90s were for the show before that "New Class" took over. Most of us just remember the armpit sniffing and the red jumpsuits, but there's a weird, beautiful darkness behind those characters that you don't really see in modern sketch comedy.
If you grew up watching those Molly Shannon skits SNL fans still obsess over, you probably remember the chaos. She wasn't just "funny." She was physically dangerous. She would throw herself into piles of metal folding chairs with a level of commitment that makes you wonder how she’s still walking.
The Catholic Schoolgirl Who Became a Titan
Everyone knows Mary Katherine Gallagher. The plaid skirt, the frizzy hair, the "Superstar!" pose. But if you look at the early appearances—specifically the debut in 1995 with Gabriel Byrne—there’s this creepy, desperate energy that actually feels kind of heavy.
She wasn't just a quirky kid. She was an outcast processing a level of inner turmoil that most SNL characters never touch. Molly has talked openly in her memoir, Hello Molly!, about how Mary Katherine was actually born from her own grief after losing her mother and sister in a car accident when she was just four.
That "armpit sniffing" thing? It’s not just a random gross-out gag. It’s a nervous tic. It’s a survival mechanism. When you realize the character is essentially a vessel for a young girl's unprocessed trauma, the comedy gets way deeper. It's why we still talk about her. She wasn't a caricature; she was a human being who just happened to be hilarious.
Kick, Stretch, and Kick: The Sally O'Malley Phenomenon
Then you have Sally O'Malley. "I'm 50! And I like to kick, stretch, and KICK!"

Honestly, it’s one of the best physical comedy bits in the history of the show. The way she yanks those high-waisted red pants up so high it looks painful? Classic.
What's wild is that Sally O'Malley was essentially Molly’s way of saying "I'm not done yet." In an industry that usually tosses women aside the second they hit 40, Sally was this middle-aged explosion of confidence. She didn't care that she didn't fit the "look" of a Rockette. She was going to do those kicks anyway.
I remember watching the 50th Anniversary Special recently where she brought the character back with Emma Stone. She's in her 60s now and still doing the kicks. That’s not just a skit; it’s a lifestyle at this point.
The Underrated Gems: Helen Madden and Jeannie Darcy
While Mary Katherine and Sally get the most YouTube views, the "real ones" know that Helen Madden is the peak of Molly's SNL tenure.
"I love it! I love it! I love it!"

As the "Joyologist," Helen Madden was this satire of the toxic positivity movement before that was even a term. She’d be talking to someone like Matthew Broderick, vibrating with this manic, fake happiness that felt like it was about to snap at any second. It was high-level social commentary disguised as a lady shouting in a pink suit.
And then there's Jeannie Darcy.
Don't get me started. Don't even get me started.
The mullet, the monotone delivery, the terrible jokes. It’s a masterclass in "anti-comedy." Most actors are terrified of being unfunny on stage. Molly Shannon leaned into it so hard it became a different kind of funny. It’s that willingness to be truly awkward that separates the legends from the people who just want to be liked.
Why Those Sketches Changed Everything
Before Molly and the 1995 cast (Will Ferrell, Cheri Oteri, Darrell Hammond), SNL was very male-heavy and often focused on political impressions or "cool guy" comedy.
Molly brought a raw, feminine weirdness that opened the doors for people like Kristen Wiig and Kate McKinnon. You can see the DNA of Mary Katherine Gallagher in almost every "weird girl" character that followed.

She also mastered the "repeatable catchphrase" era. In the late 90s, everyone was shouting "Superstar!" or "I'm 50!" at parties. It was a cultural shorthand. But unlike some other recurring characters that get annoying after three appearances, Molly's characters had enough heart to stay fresh. You were rooting for them. You wanted Mary Katherine to get the guy (even if the guy was Will Ferrell in a bowl cut).
Ranking the Best Molly Shannon Skits SNL Produced
If you're going down a rabbit hole tonight, these are the ones you absolutely have to watch to understand her range:
- The 1999 Rockettes Audition with Danny DeVito. This is the definitive Sally O'Malley. The contrast between her energy and DeVito’s confusion is perfect.
- The "Delicious Dish" with Alec Baldwin. Everyone talks about the "Schweddy Balls," but watch Molly’s face. She and Ana Gasteyer created this incredible, hushed NPR energy that makes the double entendres work.
- The Whitney Houston Sing-Off. Molly's impression of Courtney Love was great, but her Mary Katherine trying to out-sing a peak Whitney Houston is a fever dream.
- Pretty Living with Helen Madden. Specifically the ones where she explains her "joyology" to guests who are clearly miserable.
What We Can Learn From the "Superstar"
Molly Shannon’s career is basically a lesson in fearless commitment. She didn't care about looking pretty or being the "straight man" in a scene. She wanted to feel something, and she wanted the audience to feel it too.
Whether it was the "Dog Show" sketches with Miss Simmons or her spot-on impressions of Monica Lewinsky, she always played it with 100% sincerity. That’s the secret sauce. You can’t fake that kind of energy.
If you haven't seen her return to host in 2023 or her appearances in the 2025/2026 specials, go find them. She hasn't lost a step. She still brings that same "I might break a rib for this laugh" vibe that made us fall in love with her in the first place.
The next step is easy: Head over to the SNL YouTube channel or Peacock and search for the "St. Monica Talent Auditions." It’s the origin story of a comedy legend, and it's just as chaotic today as it was thirty years ago.
Actionable Insight: If you're a fan of Molly's SNL work, her book Hello Molly! is a mandatory read. It reframes almost every character she played and gives you a much deeper appreciation for the "superstar" who turned her own life's hurdles into the most iconic comedy of a generation.
