Jimmy is a piano student of Lois Griffin's that appeared in "Wasted Talent". His practices annoy her infant son Stewie while the latter is watching television. Stewie decides to beat him up for it while Lois had walked out of the room. Afraid of even worse punishment from Stewie, he lies when asked what had happened. She had hoped he would represent her at the upcoming competition.
Jimmy is voiced by Jonathan Osser.
