Sheldon: Will you at least stipulate that Star Trek IV: The Voyage Home is inarguably the best?
Raj: I have 3 words for you: Wrath of Khan.

Sheldon: What's your favorite fruit?
Stephanie: Strawberries.
Sheldon: Mmm, technically not a fruit, but all right.

Sheldon: Well, this is very pleasant.
Leonard: I'm glad you're enjoying yourself.
Sheldon: And you said there would never be enough pasta for the three of us.

Sheldon: I spent so much of my childhood at that hospital. When I was 12, I got to ride there in a helicopter.
Stephanie: What? What happened?
Sheldon: Radiation burns. A little mishap while I was building my own CAT scanner.
Stephanie: I'm sorry, you tried to build your own CAT scanner?
Sheldon: No, I didn't try, I succeeded.

Sheldon: Fellow warriors, this is Sheldor the Conqueror. We are about to enter Atzel's fortress. Now, this is a long run, so let's do another bladder check. All right, Barry, we'll wait for you again, but you really should see a doctor.

Sheldon: Just when I think I've gotten the hang of sarcasm.

Sheldon: You're in my bedroom.
Penny: Yeah, Leonard gave me an emergency key.
Sheldon: People can't be in my bedroom.

Penny: Can we go talk in the living room?
Sheldon: I'm not wearing pajama bottoms.
Penny: Why not?
Sheldon: I spilled grape juice.
Penny: Well, wear different pajamas.
Sheldon: I can't wear different pajamas. These are my Monday pajamas.

Tom: I'm sorry, dude, she didn't look anything like her picture.
Leonard: They never do.

Raj: Hey, buddy, I'm gonna be in People Magazine.
Charlie Sheen: Yeah, call me when you're on the cover.

Sheldon: We're gonna have to stop at Pottery Barn on our way to work. I bought these Star Wars sheets, but they turned out to be much too stimulating to be compatible with a good night's sleep. I don't like the way Darth Vader stares at me.

Sheldon: Just because your career's been stagnant for a few years, that's no reason to give up.

Leonard: Didn't I tell you I'd be working nights and you'd have to make others arrangements?
Sheldon: You did.
Leonard: And?
Sheldon: I didn't.

Sheldon: How am I gonna get to work.
Leonard: Take the bus.
Sheldon: But I can't take the bus. They don't have seat belts. And they won't let you latch yourself to the seat with bungee chords.
Leonard: You tried to latch yourself to the seat with bungee chords?
Sheldon: I didn't try, I succeeded. For some reason, it alarmed the other passengers and I was asked to de-bus.

Sheldon: You have to drive me to work.
Penny: Yeah, I really don't think I do.
Sheldon: But I don't drive and I can't take the bus.
Penny: Alright, honey, you'll be fine as long as you don't do that bungee chord thing.
