Ryan and Emma get into dating signals and unwritten rules brought up by Season 2 Episode 4 "The Phone Message."

Ryan, like George, dreams of having 365 pairs of underwear. Emma likes "I Love Lucy" but Ryan has never seen a single episode. Emma wants to have guys call the next day if they want and Ryan used to live next to the Polar bottling factory before millennials killed soda. Also, Emma wants any future dating partners to know that with her, coffee means coffee.

Meanwhile, Mike was too young to go to Vietnam but also too old to go to World War II, and he loves jackets with interesting linings.
