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: 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?"

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?

Bernadette: Anyway, it'll be a nice surprise for the boys. And Howie doesn't think I take his interests seriously, so hopefully this will keep him fooled for a while.

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!

Amy: Arthur passing away was harder on Sheldon than he's ready to admit. I'm really hoping this will cheer him up.
Bernadette: Me too. Although it might have been thoughtless of us to bake a Death Star cake.
Amy: No, it combines two of Sheldon's favorite things: chocolate chips and the ability to destroy a planet at the touch of a button.

Raj: Hey, Penny. Happy Star Wars day!
Penny: Okay.

Raj: Can I make you breakfast? Admiral Ackbar's Snack Bar is open for business!

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.

Howard: Why're you being so quiet? You upset or are you just rebooting?

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

Professor Proton: We'll be right back after I fire my writers.

Professor Proton: This is something interesting, boys and girls. After an owl eats, he spits up part of his meal, that he can't digest, in the form of a pellet. Isn't that a hoot?

Sheldon: Oh, I'm not going to the funeral.
Amy: Why not?
Sheldon: All those people blowing their noses. You can't tell the sick from the sad.

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