Meanwhile, Leonard Hofstadter (Johnny Galecki) and Penny (Kaley Cuoco) prepare Thanksgiving dinner at home for the gang. When he realizes she does not know his birthday, he proceeds to list personal things he knows about her but accidentally reveals his knowing that she hates the orange lingerie he bought her, which she only disclosed in her journal. To apologize for reading it without permission, Leonard dances in the lingerie, asking Penny to post an image of him onto her social media as punishment. Howard, Raj, Bernadette, and Emily arrive at the apartment around this time, to Leonard's embarrassment.
