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.
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. However, when Stan returns to the kitchen after all his dad's items have been put in the bag there is no sign of the record player in the other room.
Factual error: Roger receives movies for his projector. When he plays it there is a tiny image and the 20th Century Fox logo. Then after Roger hits the projector and it turns to the window the 3, 2, 1 countdown is played. Normally it would go the 3, 2, 1 countdown first, then the 20th Century Fox logo.
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.
