Amy: Sheldon, what's wrong?
Sheldon: I wanted to let you know I'll be spending your birthday with you.
Sheldon: See, I had tickets to the Star Wars premiere that night, but Professor Proton came to me in a dream, dressed as Obi-Wan Kenobi, and convinced me that I should be with you.
Sheldon: I'll let you get back to sleep now. Good night.
Amy: Good night. Uh, Sheldon, were you actually not going to spend my birthday with me?
Sheldon: (feigning sleepiness) It's late, gotta go, bye.
