Continuity mistake: When Jenny holds the magnifying glass, her hand and Mitch's disappear in the close-up. (01:07:49)
Revealing mistake: When the boys take the laundry basket upstairs, there's a shot from in front, and one can see none of the four family members is inside. The filmmakers didn't even bother to place toy figures inside.
Visible crew/equipment: After Holly comes over with the CDs, sour cream, and bubble machine, Jenny then shuts the front door. When Jenny walks toward the camera, just as this shot begins to transition into the next shot, we can see the green T-mark taped to the floor, and a bit of the red T-mark as well, where the two girls stood a moment before. (00:38:20)
Revealing mistake: While Wayne, Diane, Patty, and Gordon are in the laundry basket, Adam and Mitch carry that basket upstairs. When Mitch says, "I bet my parents wish I didn't have a medical problem," the camera turns to follow the boys as they walk up the stairs, and the left wall (with striped wallpaper) of the staircase is missing to accommodate the camera filming from that angle. It's visible again when Mitch says, "And I feel fine." (00:35:35)
Continuity mistake: While the four parents are atop Adam's chest of drawers, the red Britannica Junior Encyclopædia behind Adam's Sharkruiser has its spine facing out, and we see its volume 16. However, when Wayne, Gordon, Diane, and Patty are seated inside the Sharkruiser and begin to take off down the track, the Britannica behind them is now volume 20. (00:30:20 - 00:32:15)
Continuity mistake: In Adam's room, the yellow Hot Wheels track with the parked Sharkruiser, that is set atop Adam's chest of drawers, repeatedly alternates between having an extended track that continues to run under the books, or having an open track end in front of the book that lies flat on the chest surface. (00:30:05)
Continuity mistake: While the group hides from the cockroach, they check to see where she is, and the previous turds they found next to the wall have suddenly vanished.
Continuity mistake: Trey grabs two bags of chips and tosses one. A shot later, he is bending down, empty-handed, grabbing the same bag again.
Answer: As wayne enters the car he says, "Too bad Adam wasn't playing with the Splittin' Image, huh? That was cherry", to which his brother replies, "Yeah, but the Twin Mill was Faster."The Twin Mill and Splittin' Image are two popular Hot wheel cars that debuted in 1969.
