The guys rush to buy tickets to the new Star Wars movie before they sell out.

Sheldon and Leonard talk with Penny about how excited they are to see the movie on Thursday night. Penny points out that Thursday is also Amy's birthday, and that he should be spending time with her rather than seeing the movie.

Professor Proton comes to Sheldon in a dream and helps him realize that he needs to spend time with Amy on her birthday and make sure she knows how important she is to him.

Sheldon goes to see Penny and Bernadette to ask for their help choosing which gift to give Amy for her birthday. One of his options is to have coitus with her.

The guys try to figure out who to give Sheldon's ticket to. They consider Stewart until Wil Wheaton walks in.

Penny and Bernadette help Sheldon decide on the gift, which will be to finally sleep with Amy.

Wil shows up to the movie dressed as Mr. Spock from Star Trek, and the audience boos him.

Amy prepares for Sheldon to come over, with low lighting and candles.

He arrives, and she tells him she knows his gift. Both of them are nervous, but they finally make it happen.
