A waitress is listed in the closing credits, but no waitress appears in the episode.
At the start of this episode, Howard and Carol don't seem to know each other. However, in an earlier episode, "Anything Happen While I Was Gone?", both attended a party to watch slides of Bob and Emily's Mexican vaction. Howard even hit on Carol at the party.
Goof: In the scene where Bob and Cynthia meet, just about the time Cynthia leaves the room, what appears to be a coat rack with a coat hanging on it moves into the shot on the right side of the screen, even though the camera does not move.
The closing credits for this episode were taken from the original pilot. The picture credit for Peter Bonerz was not part of this episode. Also, the shot of Bob's office in closing scene #2 was of the original set from the unaired pilot.
Notice how the steps to the Hartley's front door have changed from three to two.
Bob's mother's name was Eleanor in this episode. In later episodes, Bob's mother's name is Martha and his sister's name is Ellen (similar to Eleanor).
