The clean shirt Nanny puts on Doyle reads "Women belong in the House... and the Senate."
Sean Gunn (Kirk Gleason) and Gregg Henry (Mitchum Huntzberger) have both appeared in the movie 'Guardians of the Galaxy''. They played Kraglin/On Set Rocket and Grandpa respectively.
Parts of the interior of the Huntzberger mansion were filmed at Doheny Mansion in Los Angeles, California. The same location can be seen in The Princess Diaries (2001). The Pompeian Room has an iridescent Tiffany glass dome as its core centerpiece which Rory talks about and marble pillars can be seen at the ball that Mia is introduced.
Neither Richard nor Emily appear in this episode.
