JJ Hibbert is the first son of Julius Hibbert. He is usually seen with the Hibbert Family.
His first notable role was when he was riding with his folks to a restaurant for dinner and deciding where to have dinner along the way. He answers "Professor V.J. Cornucopia's Fantastic Foodmagorium and Great American Steakery!" After Dr. Hibbert sees Moe's Tavern, he suggests they eat there, expecting a family restaurant. But when they see that it's actually a bar, they leave promptly and search once again for a real family restaurant.
