Carrie adds batter to the waffle iron and then turns to look at Doug. When she turns back to pour more batter, it is less then what was there moments ago.
Doug asks for, and receives, his photographs from the store clerk. Doug simply walks away with the items without paying for them, and the clerk does not ask for payment. This occurs at the 13:05 minute mark in this episode.
When Carrie is attempting to make waffles for Doug and turns away from the waffle iron to face him, a cabinet door behind her closes by an unseen hand.
When Carrie prepares breakfast while wearing lingerie, the wall cabinets (with small corner shelves attached) on the right of the kitchen sink are quickly swung away, well inside the shot. Subsequent shots in the same scene first show the small corner shelves in place, then removed due to the cabinets (with attached corner shelves) having been swung away.
(at around 9 mins) Doug and Carrie taking a SCUBA class at the pool. As Doug goes under water for a prolonged period the camera cuts to Carrie and the camera crew is visible on the pool deck in the background.
In the pool scene right after Doug goes underwater the camera goes to Carrie , also in the pool, looking over her shoulder at him, at the 10:28 mark, and to the left you can see clearly the camera and next to that one of the crew laying on his side.
