When Pam is telling Jim in the garage that she loves the house, and asking if they have to sleep in Jim's parents' bedroom, what looks like a wire from the boom mic at the top of the screen, is actually a wire from the garage door, which can be seen when Jim opens the garage.
Jim tells Pam that he purchased his parents' house without using a realtor but he pronounces it incorrectly, as 'ree-la-tor'. This is a common mispronunciation. Response: This nonstandard pronunciation is common enough to not be an error.
