Who Voices Andy and Ollie in Bob's Burgers? The Actors Behind the Twins

In the animated comedy series Bob's Burgers, the hyperactive twin brothers Andy and Ollie Pesto are voiced by real-life sisters and comedians Laura Silverman (voicing Andy Pesto) and Sarah Silverman (voicing Ollie Pesto). Their real-life sibling dynamic provides the distinct comedic timing, rapid-fire unison lines, and codependent chemistry that define the characters.

Overview of Andy and Ollie Pesto

Andy and Ollie Pesto are among the most recognizable recurring side characters in Bob's Burgers. Introduced early in the series, the twins are the younger sons of Jimmy Pesto, owner of Jimmy Pesto's Pizzeria and the primary business rival of Bob Belcher. Despite the intense feud between their father and Bob, Andy and Ollie maintain a friendly, albeit chaotic, relationship with the Belcher children, particularly Louise Belcher, who frequently manipulates their extreme gullibility for her elaborate schemes.

The defining trait of Andy and Ollie is their extreme, surreal codependency. They operate almost as a single entity split between two bodies. They experience anxiety when separated by even short distances, frequently insist on holding hands while running, and share absurdly unified physical sensations—such as believing one brother can feel the itch when the other scratches his back.

Key characteristics of the Pesto twins include:

• Unison Dialogue: They frequently complete each other's sentences or shout phrase fragments in alternating bursts.
• Blind Loyalty to Louise: Despite being repeatedly placed in precarious or embarrassing situations by Louise, they view her with absolute trust and adoration.
• Childlike Naivety: Unlike their older brother Jimmy Jr., who is driven by romantic angst and dancing, Andy and Ollie operate in a realm of pure, unvarnished childhood innocence and literal-mindedness.

Meet the Voice Actor Behind Andy: Laura Silverman

Laura Silverman lends her voice to Andy Pesto, the twin wearing the yellow shirt and blue shorts. Laura is an accomplished actress, writer, and voice performer whose career in alternative comedy and adult animation spans several decades.

Early Career and Comedy Roots

Laura Silverman first gained major prominence in the voice acting world during the mid-1990s. She starred as Laura, the deadpan receptionist, in the critically acclaimed animated series Dr. Katz, Professional Therapist (1995–1999). Her flat, dry delivery and sharp comedic timing on the show established her as a key figure in modern voice acting for prime-time and cable animation.

Beyond voice work, Laura has built an extensive live-action television filmography. She co-starred alongside Lisa Kudrow in HBO’s critically acclaimed satire The Comeback, playing Jane, the documentary producer capturing the lead character's tragicomic reality television reboot. Her television credits also include guest appearances on Nurse Jackie, Curb Your Enthusiasm, Master of Sex, and Adventure Time.

Vocal Approach to Andy Pesto

To play Andy, Laura pitched her voice into an energetic, slightly raspy young boy's register. Andy often acts as the slightly more vocal or decisive half of the pair, initiating physical actions or responding to commands from adults before Ollie repeats or builds upon them. Laura balances Andy’s manic energy with a subtle deadpan undertone, anchoring the absurd dialogue in earnest childlike sincerity.

Meet the Voice Actor Behind Ollie: Sarah Silverman

Sarah Silverman voices Ollie Pesto, the twin wearing the light green shirt and blue shorts. Sarah is a two-time Primetime Emmy Award-winning comedian, writer, actress, and producer known internationally for her stand-up specials, television shows, and film roles.

Career Milestones and Voice Performance

Sarah Silverman broke into national prominence as a writer and cast member on Saturday Night Live in the early 1990s before creating and starring in Comedy Central's The Sarah Silverman Program (2007–2010), which earned her a Primetime Emmy nomination for Outstanding Lead Actress in a Comedy Series. Her stand-up comedy specials, including We Are Miracles and A Speck of Dust, established her as one of the most influential comedic voices of her generation.

In addition to her live-action roles in films such as School of Rock, I Smile Back, and Maestro, Sarah has achieved widespread success in feature film animation. Most notably, she voiced Vanellope von Schweetz, one of the main leads in Disney's hit animated film Wreck-It Ralph (2012) and its 2018 sequel Ralph Breaks the Internet.

Vocal Approach to Ollie Pesto

For Ollie Pesto, Sarah crafts a voice that mirrors her sister Laura’s pitch while introducing slight variations in rhythm and emphasis. Ollie is often the twin who voices the most bizarre, abstract observations. Sarah plays Ollie with an eager, wide-eyed vulnerability, creating a seamless counterpart to Laura’s performance as Andy.

The Historical Connection: Loren Bouchard and the Silverman Sisters

The casting of Laura and Sarah Silverman in Bob's Burgers was not an accident of open auditions; it stems from a creative relationship dating back to the mid-1990s.

Series creator Loren Bouchard began his career as a producer and writer on Dr. Katz, Professional Therapist, where he worked directly with Laura Silverman during her tenure as the character Laura. When Bouchard later co-created Home Movies and eventually created Bob's Burgers, he regularly collaborated with actors from his early career network.

   • Laura Silverman (Voice of Laura)
2. 2011: Bob's Burgers Launch

   • Casts Laura & Sarah Silverman as Twins

Recognizing that Andy and Ollie required a rare level of vocal chemistry to execute rapid, overlapping twin dialogue, Bouchard and the production team brought in both Laura and Sarah. Casting actual sisters allowed the show to tap into genuine familial cadence, shared vocal traits, and decades of natural conversational flow.

Performance Dynamics: How the Sisters Record Their Roles

Recording dialogue for animated characters who constantly interrupt, overlap, and repeat each other presents unique technical challenges in animation production.

Combined Session Dynamics

While many voice actors in animated television record their lines individually in solo recording booths due to scheduling constraints, the producers of Bob's Burgers frequently attempt to record ensemble scenes together whenever possible. For Laura and Sarah Silverman, recording in the same room or on linked audio sessions allows them to improvise timing.

When delivering iconic unison lines—such as shouting their signature introductions ("I'm Andy!", "I'm Ollie!")—the sisters leverage natural sibling pitch familiarity. Because their natural speaking voices share similar vocal tract geometry and tonal qualities, pitching their voices up into young boys' registers produces a matched sound that is difficult for unrelated voice actors to replicate.

Improvised Comedy and Rhythm

The writers of Bob's Burgers provide scripted dialogue, but the cast is encouraged to adjust phrasing during table reads and record passes. The Silverman sisters frequently adjust the pacing of Andy and Ollie's back-and-forth banter, introducing slight stutters, simultaneous laughter, or overlapping phrases that give the twins an unscripted, chaotic feel.

Key Episodes Highlighting Andy and Ollie Pesto

Throughout the run of Bob's Burgers, several key episodes showcase the voice acting performances of Laura and Sarah Silverman:

1. "The Belchies" (Season 2, Episode 1)

When the Belcher kids explore an abandoned taffy factory looking for hidden treasure, Andy and Ollie tag along. The episode highlights their complete disregard for personal safety and absolute dependence on each other, culminating in their refusal to leave each other behind during a wall collapse.

2. "Unbearable Like-Likeness of Gene" (Season 3, Episode 8)

This episode features memorable interaction between the twins and Louise. When Louise uses the twins as proxy security guards or henchmen, the Silvermans deliver performances that emphasize the boys' blind compliance and absurd, literal interpretation of orders.

3. "Carpe Morn-ing" (Season 9, Episode 16)

Andy and Ollie are separated during a school assignment, triggering an existential crisis for both boys. Laura and Sarah showcase their comedic range, playing up the dramatic horror the twins feel when forced to operate as independent individuals.

4. "The Plight Before Christmas" (Season 13, Episode 10)

In a rare moment of emotional weight, the twins participate in the school's holiday pageant. The Silvermans deliver a performance that balances their traditional bizarre comedy with genuine heart, illustrating how the twins function within the broader community of Wagstaff School.

Comparing the Pesto Twins and Voice Cast

To better understand how the characters and voice performers align, the table below provides a side-by-side comparison of Andy and Ollie Pesto alongside their respective voice actors.

The Broader Pesto Family Voice Ensemble

The performance of the Silverman sisters exists within the larger vocal ecosystem of the Pesto family. Understanding how Andy and Ollie fit into the Pesto household requires looking at the rest of the voice cast representing the family:

Jimmy Pesto Sr.

The patriarch of the Pesto family and owner of Jimmy Pesto's Pizzeria was originally voiced by Jay Johnston. In late 2023, experienced voice actor Eric Bauza officially took over the role of Jimmy Pesto Sr. The elder Pesto's loud, overbearing demeanor contrasts sharply with the high-pitched, soft-hearted nature of his twin sons.

Jimmy Pesto Jr.

The eldest Pesto son, Jimmy Jr., is voiced by H. Jon Benjamin, who also voices the show's main protagonist, Bob Belcher. Benjamin uses a distinctive lisped, emotional delivery for Jimmy Jr.

  • Jimmy Pesto Sr.: Voiced by Jay Johnston (succeeded by Eric Bauza)
  • Jimmy Pesto Jr.: Voiced by H. Jon Benjamin (also voices Bob Belcher)
  • Pesto Twins: Voiced by Laura & Sarah Silverman (real-life sisters)

The dynamic between Jimmy Jr. and the twins highlights a clear divide in the household: while Jimmy Jr. is consumed by teenage angst and romantic frustration, Andy and Ollie exist in a state of perpetual, shared childhood bliss.
