Continuity mistake: The first time Bob finds his turkey in the toilet, he puts it in a trash can and lays it on the living room coffee table for a family discussion. The camera zooms in on Louise and when it zooms out, the turkey is not on the table anymore. When it shows the table a second time, the turkey reappears.

Other mistake: After the turkeys start attacking in "The Running of the Turkeys", Mr. Fishoder and his brother start running. In that clip a Turkey pops out the side of a guy's head. Look in the mid lower right side. Looks like a design error. Pretty big error, no slow down needed to see it. (00:05:20)
Aquaticism - S7-E14
Continuity mistake: Near the end, when Roger is talking to Judy, he has a tie on. But in side shots of him, he has no tie on.

Burger Wars - S1-E10
Continuity mistake: As Mr. Fischoeder talks, the plate of Meatsiah burgers in front of him disappears and reappears between shots.
Continuity mistake: The pillow disappears and reappears between shots while Gene is on the bed. Interestingly, the wrinkles his feet make in the pillow can still be seen floating in midair in the shot where the pillow itself is missing.
Continuity mistake: When Linda closes Louise's bedroom door after giving her the melted toy, the doorknob is on the right hand side. In the next shot, it's on the left hand side.
Continuity mistake: Towards the end of the episode, Sazerac declares Peter Pescadero the winner of the magic contest and says Peter's prize is a check for $500. However, when we see close-ups of Peter performing a quick magic trick with the check, the check reads "Five Thousand Dollars."
Character mistake: The math test Tina gets a D on has #5 marked wrong. However it is correct. (Additionally it seems improbable she would actually get #3 and #4 wrong since she obviously understood the concept of how to do the problem and only had a problem with the division for some reason, and these questions didn't require division).
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)
Audio problem: When Bob is being offered to drink from Beta, Bob asks which end to drink from and Pud responds "Dealer's choice." However it's Hefty Jeff's voice instead of Pud. (00:05:49)
Sacred Cow - S1-E3
Continuity mistake: When Randy mentions shooting in infrared it cuts to nighttime at the petting zoo, and in this first shot the boom operator is not wearing a wrist sweatband on either wrist, but in the next shot from within their camera lens taping in infrared, he is suddenly wearing the wrist sweatband on his right wrist, which then switches to his left wrist in the next shot. (00:16:00)
Sacred Cow - S1-E3
Continuity mistake: Throughout the episode Randy's buttons switch from the right to left side and back again repeatedly, even within the same shot. During breakfast with the cow in the kitchen, Linda's buttons repeatedly switch sides. Then, Teddy's buttons switch sides when he signs the release.
Other mistake: When Bob and Louise are trying get the theater for the Hawk and Chick film festival, the employee tells them the last showing on Saturday at 11 pm. However, after the film is shown, Bob makes a remark about the time and asks if it is a school night. Gene says yes and he has a big test the next day. If the film festival happened on Saturday, then the next day would be Sunday. There would not be school.
Like Gene for Chocolate - S7-E12
Continuity mistake: When we first see the restaurant, the burger of the day board is partially seen and we see "bites." When we next see the burger of the day it's "citizen kale burger" and "bites" isn't seen anywhere.
Other mistake: When Tina is writing in her diary and we hear the voice-over she says "So, it's a really great bang for your buck-ing bronco" but when we see the diary it reads "So it's really bang for your buck-ing bronco."
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.
Continuity mistake: When Jimmy Jr. Comes up to Tina, Gene's lunch tray has no hot dog or milk, but when it cuts to the other angle, there's now a hot dog and milk.
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)
