The Cook, the Steve, the Gayle, & Her Lover - S6-E6
Continuity mistake: In this episode, the whole family is surprised that Gayle is dating Mr. Frond. But in S6-E4, they know Gayle is dating Mr. Frond because Gayle is upset he went to his aunt's for Thanksgiving.
Suggested correction: That's because the episodes were aired out of order. This episode (production code 5ASA12) was produced before "Gayle Makin' Bob Sled" (production code 5ASA17). It's not a mistake for the show. The network decided to air the Halloween, Thanksgiving, and Christmas episodes first so they could air before the respective holidays.
Other mistake: Tina ends up in second place after joining the KIS racer. In the next scene, the family is shown eating dinner. They are shown eating their meal from what is Tina's bedroom and not the kitchen (the room with the fire escape is the kitchen). (00:13:07)
The Belchies - S2-E1
Continuity mistake: After they escape the tunnels, Tina's shirt instantly brightens in colour after she comes to a standstill.
Prank You for Being a Friend - S10-E22
Continuity mistake: When Louise is in Mr. Frond's office taking about Kaylee, in shots of both of them, there's no file on the table. But in shots of Mr. Frond, there's a folder next to him.
Continuity mistake: When Linda and the kids are walking back home, Linda doesn't have a fire hat on. But in the shot of just her, she's wearing one.
Factual error: Linda calls up Jen the babysitter to come watch over the Belcher kids, so she and Bob can go to Maya and Beckett's loft "party." Jen is in her room talking to Linda over the phone, however her screen still has the red (decline call) button and the green (answer call) button with Linda's name as she talks on the phone. There should only be the 'hang up' button with Linda's name and a running time of the duration of their call. (00:04:22)
The Secret Ceramics Room of Secrets - S8-E9
Continuity mistake: At lunch, Gene has a straw in his milk. But in shots of just Gene and Louise, there's no straw.
Burgerboss - S2-E4
Other mistake: Throughout the episode, the buttons on the video game change or disappear in some shots. For example, when Bob first asks for Darryl's help, you can see there's no buttons on the game.
Continuity mistake: Part of the plot of the episode is the port-a-potties being in front of Bob's restaurant. But on the day of the parade, there's a shot of The Land Ship going down the street and there are no port-a-potties in front of the restaurant. When Jimmy comes over to make fun of Bob, they're back in front of the restaurant.
Itty Bitty Ditty Committee - S5-E17
Continuity mistake: Gene's keyboard has a set of 3 black keys on both ends. But in the flashback when he's in bed with it, the end has a set of 2 black keys.
Burgerboss - S2-E4
Other mistake: When we first see the high scores for the video game, JMC has 99,550 points. But later only has 99,520 points.
