The first sneak peek released by CBS shows Leonard, Rajesh and Howard leaving for the Star Wars: The Force Awakens premiere as Leonard says, "The wait is finally over." Penny and Bernadatte ask the boys to have fun as Raj points out, "Can't believe Sheldon gave this up."

Another promo shows Sheldon in Amy's apartment as she's lighting candles and awkwardly asks, " So... what you have in mind for tonight?" Sheldon replies, "I thought I could take you out to a nice birthday dinner. If we pick a place east of here, we might find balloons."

Amy says, "That sounds nice, but I am not really hungry right now. I thought maybe we could do presents first." Sheldon agrees and says, "I should probably tell you something about this gift..." but Amy cuts him off and says, "You mean before you give it to me?"

In the promo, Sheldon says, "May I ask you a question before I 'give it to you'?" Then he confusedly asks her, "Why are we saying, 'give it to you' like that?"
