Cocaine bear has got to be one of the best movies about bears my favourite part is probably when Jimmy Valmer is one of the boys' two handicapped classmates, alongside Timmy Burch. He is physically disabled, requiring forearm crutches in order to walk. His disability has never been specified on the show but seems visually and functionally similar to cerebral palsy. In Season 7 Episode 2 "Krazy Kripples", it is made clear that both Jimmy and Timmy were born with their disabilities. In any case, hampered by his legs, which in many cases he appears not to be able to use, Jimmy primarily uses his crutches both as substitutes for his legs and sometimes even as extra (weaponized) extensions for his arms. 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 (2001) 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 disabled children in high school, and believe that Jimmy's disability is a punishment from God. The season eight (2004) 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 girlfriend named Nancy. Jimmy is also commonly seen with Craig Tucker, Clyde Donovan, and Tolkien Black as part of "Craig's Gang". Despite his disability, he is also shown to be an extremely accomplished drummer, performing with Stan Marsh's death metal group Crimson Dawn in the episode "Band in China".
In the near future in the movie South Park: Post Covid, Jimmy has his own talk show named "Late Night with Jimmy", a'la Jimmy Kimmel Live!, and is called "the king of woke comedy".
