Bob's Burgers recently celebrated its tenth year on air which is an impressive feat for a modern television show. Though, when it comes to animated shows, hitting ten years seems to be a baby milestone since most go on for decades. Still, Bob's Burgers has managed to captivate and keep an audience amidst a crazy world.

With eleven seasons and counting, it's no surprise that Bob's Burgers has had quite the lineup of celebrity guest stars over the years. However, because these celebrities only lend their voices to the show and not their faces, fans might not always realize how big the celebrities who are voicing their favorite side characters are.

9 Max Greenfield as Boo Boo

Max Greenfield may be best known for playing Schmidtt on the Fox sitcom New Girl, but Greenfield also dabbles in the voice acting world. In fact, he's the voice behind Boo Boo, the dreamy member of the boy band Boyz 4 Now who has appeared in several episodes of Bob's Burgers over the years.

During his first appearance, Boo Boo manages to win over Louise who thinks boy bands are lame until she goes to a Boyz 4 Now concert with Tina. Later, Boo Boo goes solo for a brief period of time before eventually returning to Boyz 4 Now.

8 Jenny Slate as Tammy

Jenny Slate is no stranger to the world of voice acting having voiced several animated characters from Gidget in Secret Life of Pets to the former voice of Missy Foreman-Greenwald in Big Mouth. However, she may be most notable for her role as Mona-Lisa Saperstein on Parks and Recreation, one of NBC's best show of all time.

Slate has lent her voice to Bob's Burgers since its second season bringing to life the reoccurring character of Tammy Larsen. Tammy is your stereotypical mean girl who is constantly mean to Tina for no real reason.

7 Will Forte as "Upskirt" Kurt

Will Forte is an amazing comedy actor who starred on Saturday Night Live for over a decade. He's acted in several successful projects and has even voiced Shaggy Rodgers in the 2020 Scoob! animated movie.

Forte appeared on four episodes of Bob's Burgers and has played two roles but his most iconic is "Upskirt" Kurt. Kurt is a pilot instructor who hits it off with Linda after Bob refuses to take airplane-flying lessons with her. He gets the nickname "upskirt" Kurt after his repeated attempts at making a move on Linda.

6 Tiffany Haddish as Patricia

Not only is Tiffany Haddish a hilarious comic, but she also has a very distinct voice which makes her the perfect voice-over actress. In fact, voicing a character on Bob's Burgers isn't her only voice acting credit. Haddish voiced Tuca in the Netflix animated series Tuca & Bertie which she also executive produced.

In the world of Bob's Burgers, Haddish voices Patricia, a young woman who owns and operates Patirica's 77 Sandwiches. Right now, Patricia has only appeared in one episode in which Bob helps out at the sandwich shop after being forced to take a day off from his own restaurant.

5 Fred Armisen as Tommy

Being a cast member on Saturday Night Live might be a key requirement to landing a voice acting job on Bob's Burgers since Armisen has done both. Armisen is best known for his on-screen comedic acting but he is known to voice a character now and then.

Armisen voiced Tommy Jaronda during the third season of Bob's Burgers. Tommy appears as a replacement health inspector after Hugo decides to follow his dreams to become a nudist. At first, the Belchers love Tommy and even encourage him to sing in their restaurant. However, things take a turn when they learn that Tommy's songs aren't "family-friendly."

4 Kathryn Hahn as Jessica

From comedies to dramas there is nothing Kathryn Hahn can't do which is why it's no surprise that she's also a voice actress from time to time. In fact, she's lent her voice to some pretty iconic animation projects over the years including Apple TV+'s Central Park and American Dad. 

Hahn voices Jessica in Bob's Burgers and so far has appeared in two episodes. She first appears in season 4 when Louise is forced to have a slumber party. While Jessica's night gets off to a rough start, she wets the bed, she ultimately ends up winning over Louise, and the two become friends.

3 Jon Hamm as Toilet

While Jon Hamm may be best known for his lead role on the hit AMC drama series Mad Men, Hamm does have a comedic acting history. In fact, he's starred in the iconic sitcom 30 Rock and Unbreakable Kimmy Schmidt. He also voiced characters in several iconic animated shows and movies from SpongeBob SquarePants to, of course, Bob's Burgers.

While Hamm might be considered a sex symbol, having been on People magazine's Sexiest Man Alive list in 2008, Hamm did not get to voice a traditionally sexy character on Bob's Burgers. Instead, he voices an expensive talking toilet that Gene finds in the woods during season three.

2 Wanda Skyes as Sofa Queen

Wanda Skyes is one of the most iconic comedians and comedic actresses of our time. What some may not know is that Skyes was a contracting specialist at the NSA before leaving to pursue a career in comedy -- and thank god she did! Since then Skyes has been in some of the best comedy films and has lent her voice to several iconic animated films including Over the Hedge, the underrated Disney film Brother Bear 2, and the Ice Age franchise.

Skyws lent her voice to Bob's Burgers during season 6 where she voiced Sofa Queen, a woman who owns and is the spokesperson for the Sofa Queen furniture store. Though the Sofa Queen has only been in one episode formally, she appears periodically throughout the series via the Sofa Queen commercials.

1 Adam Driver as Art the Artist

Adam Driver has certainly become a household name in recent years, having starred in several films ranging from Academy Award-nominated films like BlacKkKlansman and Marriage Story to the Star Wars sequel trilogy.

While Driver tends to do more dark comedy material, he jumped at the opportunity to voice a character in Bob's Burgers. Driver voices Art: The Artist in the season eight two-part holiday episode.
