Continuity mistake: This episode reveals Stan has never killed anyone, even though he killed Jay Leno in Stan of Arabia: Part 1, killed Jackson's Double in It's Good To Be Queen, accidentally disintegrates one of his co-workers in I Can't Stan You, and shot a hang glider in An Apocalypse to Remember.
Continuity mistake: When the game is tied 10-10, Yao Ming and Roger are in the circle at half-court, but when Ming checks the ball back, they are out and in front of the circle and not at half-court anymore. When Roger starts to dribble, he is back at the half-court line, all without them moving.
Continuity mistake: In the scene where Francine says she used to be friends with everyone in the block, there is a cutaway of a previous neighbor couple called the McLearys.

Continuity mistake: At the convention when we first see Roger and Hayley, they pass a booth that says Costume contest registration. There is also a few people around, a poster and a movable wall. The very next shot is more of a close up of the two and the background has changed dramatically. There is now about 4-5 different stalls behind them and no sign of the previous one or the poster and wall.
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)
