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: 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.
Continuity mistake: In a scene after Teddy shows up at Helen's house, but before Helen arrives, Louise uses a picture of Helen to show that Helen has the look of a killer. In the close-ups, when the family is covering various parts of the picture, Helen has a closed mouth smile, but in subsequent shots Helen has an open-mouthed smile.
Continuity mistake: When Mr. Fishoedor enters the restaurant, Bob is cleaning a coffee pot with a rag. In the next frame, the coffee pot vanishes from Bob's hand. Later, when the perspective is changed again, the coffee pot appears on top of a blue platform.
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.
