Arthur: Most-most of my robes open ... in the back.
Sheldon:Those are your Jedi robes.
Arthur: What is this?
Sheldon: Oh! Be careful with that.
Arthur: Whoa! Oh, neato. [laughs] I'm-I'm gonna need a Band-Aid.

Sheldon: You've come to me because you're my Obi-Wan.
Arthur: I'm-I'm not ... I'm not familiar with that. Is... is-is that an ... internet.
Sheldon: Wow. You're dead so I'll let that slide.

Sheldon: Arthur! I thought you were dead.it's fantastic.
Arthur: I am. Oh, it-it's fantastic. I mean this is the longest that I've gone without running into a men's room in-in years.

Sheldon: When Darth Vader struck down Obi-Wan, did Luke cry like a baby and go to his funeral?
Penny: No. He blew up the Death Star. Why do I know this?!

Amy: And watching a bunch of goody space movies you've seen hundreds of times isn't?

Penny, there's only one cookie with something in the middle that solves life's problems, and that's an Oreo. Or a Nutter Butter, if you're in a pinch.

Penny: Hey, I don't understand why you're not upset with Amy.
Sheldon: I am. So much so that I'm gonna bring her here for dinner on our next date night.

Penny: Not always. Unless your date drives a van with an air mattress, then always.
Sheldon: Well, if it's part of the prom experience, then I'm open to it.
