Like Timmy, the humor of Jimmy's character comes from his endless optimism despite his handicap. His disability is not overtly mocked; rather his exaggerated eagerness to be a successful "handi-capable" person. Jimmy's role has more recently been expanded, bringing him more screen time and giving his character more depth. In "Professor Chaos", he is one of the final 10 chosen to be their fourth member, but ultimately he is not picked. In later seasons, he is shown hanging with Craig's Gang. He is generally popular and successful at school; he is moral and knows how to be a friend. However, he is foul-mouthed and very competitive; he took steroids just to win the Special Olympics. He and Timmy also competed against Christopher Reeve in "Krazy Kripples". Despite being foul-mouthed and competitive, he is generally well-liked and nice always looking after his friends.
