Jack's wedding was held on the (fictitious) French Caribbean island Saint Esclavage ("Saint Slavery").
Because Jack and Liz discover that they are married due to a clerical error/language misunderstanding, they have to have a lengthy meeting with NBC's Human Resources about the company's rules for dealing with situations in which married couples work together or one spouse works for the other. Tina Fey, the showrunner and star of 30 Rock, is married to Jeff Richmond, who was the show's composer and coproducer.
Tituss Burgess has a guest spot as Angie's hairdresser. He would later star in Tina Fey's show The Unbreakable Kimmy Schmidt (2015-19).
