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.

Arthur: This is weird. Most of my robes open in the back.

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

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?

Leonard: So, what did you think of your first funeral?
Penny: I don't want to be a jerk but it was kind of a bummer.

Penny: You know Klingon.
Leonard: That's true.
Penny: No, I meant that as a regret.

Howard: I think he's taking this Professor Proton thing pretty hard.
Raj: Should we try to console him?
Howard: Or should we respect his privacy in this moment of grief?
Raj: By staying here and watching the movie?
Howard: That's what good friends would do!

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

Raj: Maybe we should see how he's doing. ... But after the Cantina scene?
Howard: Obviously.

Sheldon: Look at Arthur cracking up at a joke I made. I'll never hear that joke again.
Arthur: You never heard it that time.

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

Penny: Thank you for being the emotional one in this relationship.
Leonard: I got your back

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!

Howard: Since we all agree Episode 1 isn't our favorite, why not just skip it this time?
Sheldon: Howard, I think you of all people should avoid espousing the principle that if something is not our favorite we should just get rid of it.

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.
