When Jones learns that Sheldon and his friends failed to get Comic-Con tickets, he invites them along as his guests. Penny (Kaley Cuoco), Amy (Mayim Bialik) and Bernadette (Melissa Rauch) go for afternoon tea at a tea parlor in an attempt to feel more like adults. Once they arrive, they see that only mothers and their children are there; they decide to hit the lobby bar instead. They discuss how they do not feel grown up and how being an adult is not necessarily a good thing. Production The episode features guest stars James Earl Jones and Carrie Fisher, actors from the Star Wars film series.
