Jim has two brothers; Pete, who lives in Boston, and Tom, who lives in New Jersey. They are both characterized as sharing Jim's general love of pranks but have come across as unpleasant and they somewhat bully their little brother. While Pete and Tom have been seen in several episodes, portrayed by Tug Coker, and Blake Robbins, Larissa has never been seen on screen. In the episode "Branch Wars," while the writing is not specific on which brother is being referred to, he states that his brother's wife just had another baby.
