The Big Bang Theory season 7, episode 14 airs tonight! Here’s everything you need to know about tonight’s star-studded episode, “The Convention Conundrum.”

The Big Bang Theory season 7, episode 14 will air tonight at 8:00 p.m., bringing the show’s two-week hiatus to a close. The episode, titled “The Convention Conundrum,” will include a guest appearance by legendary actor James Earl Jones, who will play himself.

The official synopsis for The Big Bang Theory season 7, episode 14 gives us the context for Sheldon’s meeting with James Earl Jones, who provided the voice of Star Wars uber-villain, Darth Vader.

After the guys can’t get Comic-Con tickets, Sheldon tries to hold his own convention and winds up spending a wild night with James Earl Jones. Meanwhile, the girls see if they can act like “grown-ups.”

Though we aren’t quite sure how Penny, Amy, and Bernadette will attempt to be “grown-ups” this week, we’re pretty sure they will win out over Sheldon. The preview for “The Convention Conundrum” sets up Sheldon’s very-un-adult adventures with Jones, while smashing the fourth wall to pieces.

After you recover from the shock learning that James Earl Jones is not Sheldon’s father, check out the sneak peek released from The Big Bang Theory season 7, episode 14. The clip shows Sheldon approaching Jones at a Chinese restaurant, and takes an unexpected twist.

But if the presence of James Earl Jones isn’t enough to excite you, worry not. Jones’ fellow Star Wars alumna Carrie Fisher (Princess Leia) will also be appearing in “The Convention Conundrum.” Judging by the image below, released by Entertainment Weekly, Fisher will not be quite as excited to spend time with Sheldon as Jones is.

The Big Bang Theory season 7, episode 14, “The Convention Conundrum,” airs tonight at 8:00 p.m. on CBS.
