Other mistake: The opening credits for season 5 show June coming out of the front door with a pitcher of what looks like iced tea, and calling for Ward, Wally and Beaver who are all working outside. But the door opens by itself as she comes out, and then closes by itself behind her. If the entire family is outside, who opened and closed the door?

Continuity mistake: As Beaver and Wally are starting upstairs after Ward asks them to go change their shirts for supper, the camera cuts from a long shot of Ward across the room in a chair reading a newspaper, wearing a light grey suit, to a medium close-up of Ward wearing a much darker suit, and then back to the light grey.
Continuity mistake: In the scene where Ward helps June carry the groceries into the house, the bag in his left arm has a loaf of bread sticking out of the top, but as they enter the kitchen the bread is sticking out of the bag in his right arm. It is not even the same size.
Continuity mistake: As the family is sitting at the breakfast table during one of the very first scenes, Beaver gets up to leave for school. The checkered napkin in his lap falls to the floor as he walks to the back door. The camera cuts back to the table where the napkin has magically reappeared.
Continuity mistake: When June is talking to Wally, she's wearing a wristwatch and her wedding ring on her left hand. But in a close-up shot of her hands while she's making a sandwich, her left hand is bare with no watch or ring. Back to the wide shot, and the watch and ring are on her hand again.
Continuity mistake: In "The Credit Card" four episodes before this one, Eddie uses the $15.00 that Wally pays him from a loan to buy a vest. Later Eddie has to give the vest to a friend in order to get back money owed to Eddie's father. But in this episode we see Eddie at Lumpy's party wearing the very same vest.
Continuity mistake: There are a couple of continuity errors in the dance scene: First, the 4 girls sitting across from the boys switch positions from one shot to the next, then the last girl (long dark hair) disappears from the row of girls entirely, only to show up on the dance floor later in the scene. She was across from (and should have been paired up with) Beaver; instead, the teacher nods toward a now-empty chair and remarks that they "ran out of girls".
