Friends with Burger-fits - S5-E3
Continuity mistake: After Mike and Mort warn Bob about the 5-lb burger at Dusty's Feedbag, Bob rushes out to save Teddy from himself. When Bob arrives and opens the restaurant's doors, there's a variety of condiments on Teddy's table in the wide shot, but in the next close-up, all the condiments have vanished.

Other mistake: At the start, Tina, Gene, and Louise announce their new hobby, and Gene holds the glass jar. When Louise says, "Ha-ha, aliens, we farted on you," note the animation of Gene's hands and the glass jar are out of sync, making the jar appear bizarre.

Other mistake: When the Belcher kids share their idea about canning, Louise places one adhesive label on the jar. In the following scenes with the kids, this jar changes its direction between shots and also mid-shot, so the label is facing out no matter the angle. Such as, when the kids go to the walk-in cooler after lowering the temperature the night before, Louise picks up the jar and its one single label always faces out.

Other mistake: When Linda checks on all the kids in the walk-in cooler, she looks down and sees the "amazing" ice floor. In the next shot of Linda's reflection, as she exclaims, "Oh, God, look at it shimmer," Linda's reflection is not backwards.

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.
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: 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.

Burger Wars - S1-E10
Continuity mistake: As Mr. Fischoeder talks, the plate of Meatsiah burgers in front of him disappears and reappears between shots.
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.
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.
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)
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.
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."
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.
