Visible crew/equipment: When Arthur comes out the basement singing Silent Night, he stops and waits a few seconds while trying to remember the next line. Carrie prompts him for this and he thanks her and walks off. As he does, the camera changes angle and a tape marker can be seen on the floor where he stopped to remember the next line in the carol. (00:03:30)
Continuity mistake: Arthur grabs a spoon to have some of the brie, camera cuts and he grabs the spoon again. You hear him take the spoon twice as well as it clangs on something. (00:04:15)

Continuity mistake: When they are talking about Carrie only having one good ovary, the napkin under Doug's hand keeps changing position. (00:15:10)
Revealing mistake: When the screen says "2 months later" the camera shakes. (00:21:20)
Continuity mistake: In this episode, Doug looks out his bedroom window and sees his parents and Arthur standing on the porch by the front door, but in season one, the episode when Richie sleeps with their neighbor, Carrie and Doug's bedroom window faces the Sacksi bedroom window.
Suggested correction: The window in this episode is the one looking out the front (same wall as headboard), but the one referenced in the episode with Richie is the side window, so a different view.
