|Voiced by||Jay Johnston|
James "Jimmy" Poplopovich, Sr, better known as Jimmy Pesto, is the owner of Jimmy Pesto's Pizzeria and is Bob's primary business rival. He is the main antagonist of the show. Jimmy is the father of Jimmy Jr., Tina's primary love interest, and twin boys Andy & Ollie Pesto. In The Belchies it is implied he is divorced from his sons mother, stating 'I thought you were at your mothers' to the twins, but her name and appearance have yet to be seen. He is voiced by Jay Johnston.
In the episode Sheesh! Cab, Bob?, Glitter, Marble, and Cha-Cha reveal to Bob that Jimmy Pesto is a regular at a fetish club called the Desire Dungeon. His nickname is "Baby Num-Nums" and is a 'Diaper Lover.'
Jimmy Pesto has seen less prominence in Season 2 as a major character to the plot, but appears in Burgerboss when Bob tries to beat Jimmy's high score on a video game when he leaves the initials to say "BOBSUX". In Tina-Rannosaurus Wrecks, Jimmy appears when he calls Bob to tell him that it was his parked car that Bob hit in the parking lot. While Bob doesn't want to sound irresponsible as a parent, he doesn't tell him that it was Tina driving the car.
In Full Bars, Jimmy Pesto gives the trick-or-treating Belcher kids oyster crackers and although he has no lines, he is seen attending the block meeting in the Belcher's restaurant in The Deepening. Another non-speaking appearance for Jimmy Pesto is in the final moments of Nude Beach where we see a shot of Jimmy inside his restaurant.
