Penny: Oh, I get it. Like C-3PO. ... What happened to me?

Leonard: The funeral's on Sunday.
Sheldon: But that's Star Wars day.
Leonard: Yeah. Off all the things about this that are sad, that might not be number one.

Bernadette: How did that get you into science?
Amy: Oh, I went to the library and took out a book on biology to see what whores did.

Penny: You're a big cry baby. You start, I'll join in.
Leonard: I am not a cry baby.
Penny: Toy Story 3.
Leonard: The toys were holding hands in a furnace!

Sheldon: I know why. You've come to me because you're my Obi-Wan.
Arthur: I'm not familiar with that. Is that an Internet?

Howard: You sure? Not even coffee? We have R2-Decaf. Maybe a nice Cafe au Leah.
Raj: And if you're not in the mood for coffee, I can always make you a Chai Tea-3PO.

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

Amy: I guess it must have been back when I was in the Girl Sprouts.
Bernadette: Girl Sprouts?
Amy: My mom made it up as an alternative to the Girl Scouts. She didn't want me selling cookies on some street corner like a whore.

Sheldon: I'm fine.
Leonard: Okay ... and yet he cried when they changed the Raisin Bran box.

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

Sheldon: Wow. You're dead, so I'm going to let that slide.

Arthur: Just make sure you appreciate those who are still there for you.
Sheldon: But I do appreciate them.

Bernadette: I got into science because I was always the smallest kid in the school. I thought if I became a scientist I could invent a formula that made me taller.
Amy: That's cute.
Bernadette: I thought it was working for a while, but then I found out my brother was just lowering the pencil marks on the door frame.

Penny: I've just never known anyone that died. I had a pet pig when I was a kid. When he died we didn't have a funeral, we had a barbecue.

Amy: We were hoping it might cheer you up.
Bernadette: And even though it meant we had to miss the movies, we could still be part of the fun.
Howard: Oh, you didn't miss anything. We just started over.
Bernadette: Son of a bitch.
