The correct title of this episode is Burger War, this is evidenced on the public catalog of the US Copyright Office, Fox's official press release, and a shirt produced with the episode names on its back for the 100th episode. Many sources including iTunes call the episode Burger Wars.
First episode to use the current style of text on the intro credits and end credits.
When Gene cuts off his rat-tail, instead of the closed captioning including the brief "Bye-Bye" musical sting, a line of dialog for the hair is shown saying, "Wait, can't we talk about this?!".
This episode was the third produced but aired as the tenth. This episode was meant to serve as the official introduction to the Pesto Family, Calvin Fischoeder, Trev, and Coach Blevins but they all first appear in episodes aired before this one. Mort's mother also makes her first appearance but doesn't speak until her second appearance in "God Rest Ye Merry Gentle-Mannequins." Bob also mentions the rent being month-to-month in "Sheesh! Cab, Bob?" which Fischoeder only implements at the end of this episode.
Hugo was supposed to appear in this episode according to a promotional image, although it was likely from a scene cut for airtime. The possible deleted scene didn't appear on the DVD release of the first season.
The book Louise reads about voodoo in this episode is called "WhoDoVooDoo."
This episode was the least watched in Season 1, with only 4.00 million households tuning in to watch it. Despite this, all episodes in seasons 5, 6, and 7 failed to reach this figure.
The episode received positive reviews from critics.
The flower vase Linda sets out on the counter disappears by the time Mr. Fishchoeder arrives at the restaurant.
Linda places a coffee down on the counter, presumably for Mr. Fischoeder to drink at the same time Bob serves him the burger, but it disappears following the close-up shot after she places it down.
Jimmy Pesto's hair that Louise cuts off keeps disappearing and reappearing on his head.
One of Pesto's burgers with an Italian flag decoration appears in a close-up shot of Bob and Linda but doesn't appear elsewhere. Interestingly the burger appears in the aforementioned promo image that got deleted. Likely missed by the animation team after the scene got cut.
In some shots the buttons on Jimmy, Jr.'s vest are on the wrong side.
