Plot hole: In the episode where Gabe wants PJ and Teddy to pretend to be his parents when his teacher wants to see them after getting in trouble at school, it is established that Gabe's elderly teacher is short-sighted. When he asks "How many fingers am I holding up" his teacher gives an incorrect answer. However, later in the episode, his teacher spots Teddy on a date at the cinema (movie theatre) and assumes she's cheating/having an affair. How could she have seen Teddy from a row in-front, when Teddy is facing the audience and not the teacher, if she couldn't see how many fingers Gabe was holding up close to her face?
Continuity mistake: The way Teddy is holding the soda and mints keeps changing between shots.
Continuity mistake: When Amy puts Gabe on the spot by asking if she's "really smokin'" for a pregnant woman, Amy strikes a pose with her water bottle in her left hand, but in the closeup the bottle is suddenly in her right hand.
