While talking in the airport, Marty, Clyde and Doug use bad accents to mimic a British client. Doug has the worst accent and apologizes for having a terrible ear for accents. This is an in-joke as in reality, Doug is played by Josh Lawson who is Australian and puts on an American accent to play Doug.
Kristen Bell (Jeannie Van Der Hooven) & Wanda Sykes (Rita) also worked together on Bad Moms (2016) & A Bad Moms Christmas (2017), as Kiki & Dr. Karl respectively.
