Corky Jimmy 'Jimbo' Jones, also known as James, Jamesbo, and Hector Gutierrez, is a student and bully at Springfield Elementary, with Dolph Starbeam, Kearney Zzyzwicz, Nelson Muntz, and the Weasels. He is a sixth grader and has been held back multiple years. Jimbo was originally introduced in the episode 'The Telltale Head' by Bart as 'the worst kid in school'. He is the second-in-command of the bullies, being their leader when Nelson isn't around, not that Nelson has any interest in hierarchic systems. Jimbo has an on-and-off friendship with Bart Simpson that depends on how badly Bart is willing to behave and whether he has any lunch money or not.
