The long-running animated sitcom follows the eccentric Belcher family who operate and live out of their own burger joint called Bob's Burgers. Father and level-headed burger chef Bob (H. Jon Benjamin); his wife Linda (John Roberts); and their children Tina (Dan Mintz), Gene (Eugene Mirman) and Louise (Kristen Schaal) try to keep the family business afloat all while getting into some wacky situations.

Naturally, Bob has plenty of competition in the food industry, none more vindictive than Jimmy Pesto.

Jimmy Pesto Sr. (Jay Johnston) operates his own Italian restaurant called Jimmy Pesto's Pizzeria right across from Bob's Burgers and typically brings in more customers. Being fully aware of his own success, Jimmy typically uses every opportunity to lord his popularity over Bob, much to the burger chef's chagrin.

As Bob's rival, Jimmy is a very prominent character in the series. However, his longtime voice actor underwent a big change.

As of Season 14, which premiered in 2023, Jay Johnston was replaced by voice actor Eric Bauza as the voice of Jimmy Pesto. The recast comes after controversy emerged surrounding Jay's political stance.
