- Because of how there's only one week until A Very Happy Glee Halloween, and this episode will still air in October, it will air on the same week as the next episode, making next week air two episodes than usual. 
- When Alissa says to Sam "Listen here, you can stay in this building and I can crack your nuts, right or left.....", it makes reference to the movie Russel Fish: The Sausage and Eggs Incident, which Chris Colfer, who currently stars in this series, starred in.
- This marks Sam's first appearance on the series.
