Leonard: It took him a long time to get comfortable around me, too.
Amy: Really? What did you do?
Leonard: Something terrible in a former life? I don't know.

Sheldon: You know what this is? And I reserve this word for those instances when it's truly reserved. This is malarkey.

Penny: Wow, you really struck a nerve. I've never heard him use the M-word before.

Leonard: May the force be with you. Get it?
Penny: Oh no, this face wasn't because I didn't get it.

Sheldon: I'm working on the Star Wars day schedule. Now, I have a window built in, after Phantom Menace, for complaining. But I'm worried an hour won't be enough time.

Sheldon: What are you doing?
Leonard: Comforting you.
Sheldon: Your heart might be in the right place, but your head, chest and arms certainly aren't.

Amy: Watching your old friend?
Sheldon: Yes. Look at him, Amy. It's such a shame. Struck down in the prime of my life.

Sheldon: Amy, mourning the inevitable is a complete waste of time.
Amy: And watching a bunch of goofy space movies you've seen a hundred times isn't?
Sheldon: If we were in a physical relationship, you've just lost sex tonight.

Sheldon: Arthur Jeffries was a scientist. I'm sure he didn't care about stupid superstitions like funerals. If he were here, I think he'd say "Enjoy Star Wars day".
Leonard: He was eighty-four. He'd say "Where's my pudding?"

Raj: Before you go, at least let me pack you some Attack of the Scones for the road.
Penny: Ohh, like Attack of the Clones. ... We are leaving right now!

Arthur: It's fantastic. This is the longest I've gone without running into a men's room in years.

Sheldon: Why are you here?
Arthur: I don't know. I was hoping I was going to haunt my ex-wife.

Sheldon: Why do I need you now?
Arthur: Well, as near as I can tell. You fell asleep watching Star Wars and now you're dreaming you're watching Star Wars.
Sheldon: So?
Arthur: Don't you see a problem there? How you're spending your limited time on earth?
Sheldon: Not at all.
Arthur: Okay. Good luck to you.

Raj: Aren't you going to get 3D glasses?
Sheldon: I brought my own. No sense in risking "bridge of nose Herpes".
Raj: Is that a real thing?
Sheldon: Well, until they invent nose condoms, I'm not finding out.

Mrs. Wolowitz: (Off screen) I'm hungry again!
Howard: It's like the world's fattest cuckoo clock.
