Continuity mistake: When Arthur is telling Carrie he has got a job, Carrie is putting out paper plates. She puts all three out and then the camera changes angle. When it does, one of the plates has moved across the table and Carrie is seen placing it in position again.
Audio problem: When Doug enters the kitchen wearing his leather jacket and tells Carrie he just got in from riding the bike, you can see the bike parked just outside the kitchen window in the backyard. If that was true it would have been heard from inside the kitchen, as motorcycles are quite loud.
