Leslie: "OK, get this. I talked with the bartender here -- her name is Lauren. And I asked her, hey, can you make up a drink for us. Our spacecraft is flying to somewhere very cold. We think it's covered with ice. Maybe some cryo-volcanism. N2, CO2. Likelihood of organic molecules. Maybe a reddish tinge. Now, what kind of a drink can you make that matches that? We're going to call it an Ultima Thule!"
