10 Iconic TV Characters Who Were Only Supposed to Be in One Episode

Some TV characters leave a lasting mark despite only appearing briefly, proving a single episode can make them iconic. These one-shot roles often steal scenes, shift storylines, or become fan favorites due to brilliant writing and standout performances.

I love how these characters can spark such strong reactions in just one appearance, sometimes outshining regulars. Here are 10 iconic TV characters who were meant for just one episode but left a huge impact.

Fingerlakes Guy – The Office (2005-2013)

Jim Carrey plays the quirky Fingerlakes Guy, a bizarre job applicant interviewing for the regional manager role at Dunder Mifflin. His brief cameo is packed with absurd humor as he sneaks away from a family vacation to attend the interview.

I laughed hard at Carrey’s wild energy, claiming he’s on a hike while clearly unfit for the job. His fleeting appearance among other big-name cameos like Will Arnett makes it a hilarious highlight of the show’s chaotic hiring process.

Joy – Mad Men (2007-2015)

Elle Fanning stars as Joy, a free-spirited nomad Don Draper meets on a California business trip. Her carefree vibe and odd fascination with Don offer a glimpse into a life without rules.

I found her brief role striking, as she pulls Don into a world of high-society wanderers, tempting him with freedom. Fanning’s ethereal performance makes Joy a memorable contrast to Don’s rigid New York life, leaving a lasting impression.

Agnes – Grace and Frankie (2015-2022)

Dolly Parton appears as Agnes, a working-class angel in the series finale, guiding Grace and Frankie in a surreal afterlife moment. Her warm presence brings a divine touch to the show’s end.

I was charmed by Parton’s grace and spunk, delivering heartfelt advice with her signature charisma. Even in just a few minutes, Agnes feels like a perfect cap to the show’s themes of friendship and resilience.

Stoop Kid – Hey Arnold! (1996-2004)

Marcus Toji voices Stoop Kid, a territorial bully who never leaves his stoop, revealed to have a fear of stepping off it. Arnold helps him face his phobia in a single episode.

I loved how this character’s tough exterior hides a relatable struggle, making his growth feel real. Toji’s performance adds depth to Stoop Kid, turning a one-off role into a fan-favorite city legend.

Philip Davidson – Brooklyn Nine-Nine (2013-2021)

Sterling K. Brown plays Philip Davidson, a dentist suspected of murder, interrogated by Jake Peralta. His calm, clever demeanor makes the intense questioning session a standout.

I was gripped by Brown’s chilling performance, holding his own against Jake’s relentless tactics. Philip’s brief appearance strengthens the bond between Jake and Holt, leaving a strong mark on the show’s dynamic.

Thumper – South Park (1997-2025)

John Postum voices Thumper, a ski instructor in Aspen who teaches Stan using simple ‘pizza’ and ‘French fries’ techniques. His earnest, goofy charm shines in a satire of underdog sports films.

I found Thumper’s enthusiasm hilarious, especially as he helps Stan take on a jock in a ski race. His brief role captures the show’s knack for turning small characters into memorable comedic gems.

Chrissy Cunningham – Stranger Things (2016-2025)

Grace Van Dien plays Chrissy Cunningham, a cheerleader tormented by hallucinations and Vecna’s curse in the season four premiere. Her tragic arc sets the stage for the show’s darker tone.

I was moved by Van Dien’s portrayal of Chrissy’s fear and vulnerability, making her more than a typical victim. Her brief but haunting presence elevates the season’s emotional stakes, lingering with viewers.

Lucille – The Walking Dead (2010-2022)

Hilarie Burton plays Lucille, Negan’s wife, in a flashback episode exploring his pre-apocalypse life. Her cancer battle and love story with Negan add depth to his complex character.

I found Burton’s performance, as Jeffrey Dean Morgan’s real-life wife, deeply touching and authentic. Lucille’s single episode transforms Negan from a villain to a tragic figure, making her unforgettable.

Soup Nazi – Seinfeld (1989-1998)

Larry Thomas plays the Soup Nazi, a strict chef with a rigid ordering system that frustrates Jerry and Elaine. His gruff demeanor and iconic ‘No soup for you!’ line became a cultural phenomenon.

I love how Thomas nails the character’s intensity, making a single episode endlessly quotable. The Soup Nazi’s brief role captures Seinfeld’s knack for turning quirky side characters into comedy legends.

Hank Scorpio – The Simpsons (1989-2025)

Albert Brooks voices Hank Scorpio, a charming yet maniacal CEO who hires Homer in ‘You Only Move Twice.’ His mix of friendly boss and evil genius, complete with a flamethrower, is pure brilliance.

I was blown away by Brooks’ rapid-fire comedy, making Scorpio a fan favorite despite one appearance. His wild energy and world-domination schemes steal the episode, cementing his place as a Simpsons icon.
