Plot hole: In the very last episode of the show, "George Decides To Sta-Local Where It's Familiar", Angie mentions that they conceived their "kids" there, referring to both Carmen and Max. However, the season four episode "George Takes a Stroll Down Memory Pain" showed flashbacks where Angie and George were living with Benny, and Angie was far along in her pregnancy with Carmen. Only Max could have been conceived in the house that they are currently living in. I want to add that in the episode 'Valentine Massacre', George says"What about the first time we made love. What were the odds in Vegas!?!"

Continuity: When Ernie is putting in the heat lamp, there is one part when he is holding a piece to it, and reaches up to put it in. In the next shot or two, he has it and puts it in again.

Continuity: When George comes upstairs to his bedroom, he closes the door carefully behind him. Then he goes to look in the mirror for a moment, and when he heads back to his bed, the door is wide open.
