When Granny is first talking to the Irish NYPD Officer, she mentions that Jed is from Taney County. The only Taney County in the US is in MIssouri. Branson is also in Taney County.
Sammy Davis Jr.'s cop is named Muldoon. This might have been a hat-tip to "Car 54, Where Are You?" in which Fred Gwynne played Officer Muldoon.
As with the previous episode, the entire episode was shot in the studio. All the New York scenes were second unit or stock footage used as rear projection and establishing shots.
