After five years, a near engagement and a breakup, Sheldon (Jim Parsons) and Amy (Mayim Bialik) will finally have sex on Thursday's The Big Bang Theory.

The problem? The big day coincides with the opening night of Star Wars: The Force Awakens, for which Sheldon has tickets. See, Amy's birthday is the same day and Sheldon has different priorities until Arthur (Bob Newhart) comes to him a dream and encourages him to spend the day with what's important to him (read: not Star Wars).

Needless to say, Sheldon heeds his advice, but he still needs some more pointers for the big night from Arthur.

Find out how it all goes down Thursday at 8/7c on CBS.
