Factual error: Robert's voyeuristic neighbors are using the same elevator as Robert does and tease him about seeing him and Amy through his bedroom window. But if they were able to see into his bedroom, they would not be using that elevator; it would be in another building. From the outside shot of his apartment building, it would be impossible to look into his bedroom.
Continuity mistake: At the end of the episode when everyone is arguing in the kitchen, the potholders next to the lasagna on the table keep changing position between shots.
Other mistake: When Amy runs out of the basement wearing Robert's pants, the pants are at full length, with the belt under her arms and the bottom of the pant legs at her ankles. When she is standing next to Robert, though, it is clear that he would have to pull the pants all the way up to his ribs for the legs to be the right length on him. Also, the pants are unzipped and the zipper pull is hanging just below Amy's breasts. Since a pants zipper is usually just an inch or so above the crotch, Amy would not be able to pull the pants that high unless there was a 12" drop between the zipper and the crotch of the pants.
Chosen answer: A Canapé is a cracker or a small, thin piece of bread or toast spread with cheese, meat, or relish and served as an appetizer.
