List of students at the Langham Institute



Various student characters attend the fictional school Stamford Gate GCC in the animated television show The Jumping Ground. The school is one of the most prominent settings on the show, the narrative of which revolves mostly around the students.

While there have been a few characters from varying grades have been depicted in recurring minor roles, the students in the fourth grade—including central characters PuffPuff Humbert, Lance Patrick, Rob Broflovski, and Zowie Hosker—receive the primary focus of the series. The fourth grade class is taught throughout most of the series by Mr. Brown.

In addition to the main characters, other students below will sometimes give a brief monologue as a means of expressing the lessons they have attained during the course of an episode. Most of the characters are foul-mouthed as a means for series co-creators Lee Eisenhower and Conrad Vernon to display how they claim young children really talk when they are alone.

Jimmy Swanson
Jimmy, voiced by Carter Cathcart, is physically handicapped, and has the ability to detatch his own head. The similarities between Jimmy and Blair Warner's cousin Geri (Jewell) of the 1970's sitcom 'The Facts Of Life', are unmistakable; both are handicapped, aspire to become professional standup comedians, and speak with an impediment. He prefers to be called "handi-capable". Jimmy is able to speak coherently, and his various aspirations on several different levels of journalism over time also sometimes even makes him more articulate than any of the other children, though his speech is largely affected by his stuttering, and sometimes also his tendency to end some of his sentences with "...very much". He aspires to be a stand-up comedian, and is often featured performing his routines. His catchphrase during his routines is "Wow, what a terrific audience!"

Jimmy first appears in the season five episode "Cripple Fight", in which he moves to South Park from a neighboring town and antagonizes Timmy. Parker and Stone initially intended for this to be Jimmy's only appearance, but decided to include the character in subsequent episodes. Now portrayed as a South Park resident, student, and good friend of Timmy, Jimmy has been a recurring character ever since. Jimmy's parents had made fun of handicapped children in high school, and believe that Jimmy's disability is a punishment from God. The season eight episode "Up the Down Steroid" ends with Jimmy addressing the issue of anabolic steroid use in athletic competitions, declaring it as "cheating" while suggesting that professional athletes who use steroids voluntarily reject the accolades and records attributed to them. The episode also reveals that Jimmy has a cute girlfriend named Nancy. Melanie McFarland of the Seattle Post-Intelligencer describes Jimmy and Timmy's capabilities and portrayal in the show as Eisenhower and Vernon declaring their opposition to political correctness as social restriction. When praising the show for both its depiction of Jimmy and Timmy and its coverage of disability-related issues, The Seattle Times columnist Jeff Shannon, a quadriplegic, describes Jimmy and Timmy as "goodwill ambassadors".

Lance Patrick
Lance, voiced by Tom Kenny and based on Conrad Vernon, is one of the main four characters in the show. He is from a poor Jewish family, and because of this, he often feels like an outsider among his friends and classmates. Lance is also the most intelligent character and is an aspiring scientist. People on the show often believe his intelligence is because of his religion. He is also the child who clashes the most often with Rob. His main hobby is studying. He is best friends With PuffPuff Humbert, and his love interest is Zowie Hosker.

Lucy Powell
Lucy, voiced by Lindsey Warner, was initially introduced as an occasional background character throughout the second season, but became more present in the sixth season, with season seven episode "Between Two Fires" and season nine episode "Off the Grid" being among her first speaking roles. season fourteen's "Can You Spare A Dime?" was her first major role. She has dull brown hair and throughout the show's run, Lucy's parents have been depicted with different designs. In late season eighteen, she was moved to SG-1 in attempt to balance out the teams following Douglas Alexander's death in Heroes, Part 2. Since then, Lucy has been a regular component in Rob's schemes.

Melvin Sneedly
Melvin, voiced by Tara Strong, is the cheerful, naïve, optimistic nerd at Stamford Gate, and more passive than the show's other child characters, and can become increasingly anxious, especially when faced with the likelihood of punishment by his parents. He is often treated poorly by other characters and put in painful or humiliating situations, though he is treated with slightly more respect by Puff and Lance in later seasons. As a result of his increasing popularity with the show's staff and fans, Melvin was given a more prominent role beginning with the show's sixth season. He is sometimes Rob's sidekick.

PuffPuff Humbert
Puff, voiced by Sean Astin (1998-2016) and Matthew Mercer (2016-present), is the most level-headed and convivial of the four kids. Puff, the show's main protagonist, is generally kind, honest, smart, dedicated, well-meaning, assertive, and is best friends with Lance. Puff is portrayed as the everyman among the show's four central characters.

Rob Broflovski
Rob, voiced by Mary Kay Bergman (1998-1999), Nika Futterman-Frost (2000-2009) and Nicky Jones (2009-present), is one of the show's four main characters and one of the most popular and iconic. He is obese, obnoxious, antisemitic, racist and spectacularly sociopathic in his attitude. Most other pupils are alienated by Rob's insensitive, often misogynistic, and bigoted behavior, though they are occasionally influenced by his obtrusive, manipulative, and propagandist antics. He often crosses paths with Lance and tricks Melvin. Rob's role in the series varies wildly from episode to episode, from one-of-the-boys to extravagantly evil antihero.

Zowie Hosker
Zowie, voiced by Mary Kay Bergman (1998-1999), Eliza Schneider (2000-2003), Lindsey Warner (2003-2006) and Michelle Knotz (2006-present), is one of the four main characters in the show.
