Continuity mistake: The vent-hood in the kitchen above the stove/island is always disappearing and reappearing. Sometimes it's there, sometimes it's not. The handles on the fridge/freezer also keep changing sides. Sometimes they are on the left, sometimes they are on the right. And the living room is always changing sizes. Sometimes they open the front door and the couch is right there, and sometimes it's several feet away from the front door.
Continuity mistake: Steve, Hayley and Francine all stand next to the door when Bullock arrives. They are all standing right next to the door in the shot where Stan adjusts their clothes. But they have magically moved a foot away from the door in the following shot where Stan opens the door. (00:03:45)Casual Person
Continuity mistake: Just as Bullock rings the doorbell, Roger oozes gunge from the left side and right side of his torso. The gunge from the right side goes on the couch and the left side goes off screen in a direction towards the door. Yet when Stan answers the door, no gunge is visible on the floor anywhere.

Continuity mistake: When Stan and Francine are first in the kitchen, a record player is briefly seen to the right of the screen.

Continuity mistake: After the last school day has ended, Stan chases Steve into a canyon Terminator 2 style to show him camp brochures. After Steve has a go at Stan about not wanting to go to camp, Francine enters the scene, knocking Stan's car out of the way. The car is almost ten meters away from Steve and Stan as she enters the scene. Francine doesn't move the car in the next shot. But in the next shot after that, the car is suddenly right next to Steve and Stan. (00:01:15)Casual Person
Continuity mistake: When Francine brings lemonade on a tray for Steve and his friends, she assumes Snot is drowning. Francine then drops the tray and it lands on the ground before jumping in the pool after him. The tray disappears when she emerges from the pool with Snot. (00:03:45)Casual Person
Continuity mistake: After Steve accidentally jabs the wood burner into Stan's penis, he screams and a avalanche occurs. Then when Stan screams a second time due to putting the cream on his penis, the avalanche happens again but the same amount of snow is on the mountain even after a load already fell off it.

Continuity mistake: When the bus driver finds Roger, the Dignity Towers Retirement Home bus is only a few feet away from them. But in the shot where Roger says "How do I get home? How do I get home?", there was no sign of any bus for many many meters. As if the bus just appeared out of nowhere. (00:09:45)Casual Person
