Raj: It's hot in here. It must be Summer.
Summer Glau: That's cute.
Raj: Really? I just made it up. Have you seen Slumdog Millionaire?
Summer Glau: Oh, yeah, I loved it.
Raj: It's loosely based on my life.

Raj: Sheldon, is there a place on this train to get alcohol?
Sheldon: Interesting that you ask. The Coast Starlight recently added the refurbished Pacific Parlour Car. Built in 1956 and originally known as the Santa Fe Lounge Car, the lower level is a theater-
Raj: Yeah-yeah, which way?
Sheldon: --and the upper level is a bar that offers wine tastings if you're going as far as Portland.

Howard: It's hot in here, it must be Summer.

Sheldon: George Smoot is a Nobel Prize-winning physicist, one of the great minds of our time. His work in black body form and anisotropy of the cosmic microwave background radiation cemented our understanding of the origin of the universe.
Penny: It's kind of a funny name, though, Smoot.
Sheldon: It's like talking to a chimp.
Penny: Okay, now that I've been completely insulted, have a good flight.

Leonard: Wow, teasing the guys at the Apple Store seems a little redundant now.
Sheldon: I don't follow.
Leonard: I wouldn't expect you to.

Penny: The theater is above a bowling alley, so it's a little noisy, but it might be the only chance I'll ever get to play Anne Frank. And the director is brilliant. He uses the bowling sounds as, like, Nazi artillery.

Leonard: We had a vote. Three of us voted for airplane. Sheldon voted for train, so we're taking the train.
Sheldon: Don't say it like that, Leonard. Say it like, "We're taking the train!"

Leonard: Excuse me, but what about me? Why don't I get a shot?
Howard: Fine, go ahead. Take a shot.
Leonard: You know, I've already got a gorgeous blond back home that I can't score with. I think I'll let you two take this one.

Sheldon: Gentlemen, this is the Coast Starlight, one of the great American trains operating on one of the classic American routes. On this side, you'll see panoramic ocean vistas inaccessible to any other form of transportation, while on your side, you'll be treated to 350 miles of Costcos, Jiffy Lubes, and cinderblock homes with above-ground pools.

Penny: Oh, I love San Francisco. I wish I was going with you.
Sheldon: I understand your envy. This is a can't miss symposium. There are going to be discussions on bio-organic cellular computer devices, the advancements in multi-threaded task completion, plus a round table on the non-equilibrium Green's function approach to the photoionization process in atoms.
Penny: When I go, I usually just get hammered and ride the cable cars.

Penny: What up moonpie!

Leonard: But look, Penny's home. Why don't we just call her, have her go in the apartment, get your flash drive and e-mail you the paper?
Sheldon: But the flash drive is in a locked drawer in my desk.
Leonard: So?
Sheldon: The key is hidden in my room.
Leonard: So?
Sheldon: Penny would have to go into my room.
Leonard: So?
Sheldon: People don't go in my room!

Sheldon: I'm confused. I thought you were involved in some sort of socially intimate pairing with Leslie Winkle.
Howard: Sheldon, let me explain to you how this works.
Sheldon: All right.
Howard: That's Summer Glau.
Sheldon: Yes.
Howard: That's it.

Howard: Hi, I'm the small package good things come in.

Raj: Actually, in India, the names of constellations are different. Where you have the Big Dipper, we have the Big Curry Pot.
Summer Glau: You're making that up.
Raj: You got me. Now what are you going to do with me?
