Trivia: The character Ted Chaough is briefly heard ordering an "Old Spanish" at a bar during the episode. This is a very quick and subtle reference to the popular cult-comedy series "30 Rock." In "30 Rock", the "Old Spanish" is a fake drink that character Cooter Burger is jokingly convinced is real as a prank by co-workers at the White House. The drink was rather nauseatingly comprised of red wine, tonic water and olives. "Mad Men" star Jon Hamm had previously co-starred on "30 Rock" and is friendly with its creator Tina Fey, thus the reference.
