Sheldon: I have one question. Is this a prank? Where you land in Houston and you've made up wanted posters which have my face with a moustache and a Spanish name, and I get arrested and deported to South America?
Howard: No.
Sheldon: Well I'm glad, because I would not have seen that coming.

Bernadette: Sheldon, when was the last time you got any sleep?
Sheldon: I don't know. 2 or 3 days. Not important. I don't need sleep, I need answers. I need to determine where in this swamp of unbalanced formulas squatteth the toad of truth.
Penny: Toad of truth? Is that a physics thing?
Leonard: No, that's a crazy thing.

Sheldon: Why hast thou forsaken me, O deity whose existence I doubt?

Sheldon: Thanks, Dad. We're gonna give them hell.

Sheldon: Oh, what fresh hell is this?

Sheldon: I don't understand why women insist on making a big production about buying clothes.
Penny: You're right. We should do what you do, have our mom send us pants from the Wal-Mart in Houston.
Sheldon: They have a man there who understands my personal style.

Sheldon: Because there's only one of me, I'm more valuable.
Penny: Right.
Sheldon: Although, Amy's already taken me out of my package and played with me.

Sheldon: No, the campus isn't safe at night. There's raccoons and undergrads just walking around like they own the place.

Sheldon: I'm not a child. I know the word 'ninny.'

Howard: Listen, I was thinking you and I could probably try to be better friends.
Sheldon: Really? I was thinking what we have now is a bit much.

Amy: You're making me worry. What's going on?
Sheldon: What's going is we're about to go to a prom and there's a great deal of pressure on young couples like us to engage in what Mr. Bob Eubanks called "makin' whoopee".

Sheldon: I didn't care for her yelling, but now that I'm not going to hear it again, I'm sad.
Leonard: If you want, I can yell at you later.
Sheldon: It won't be as good.

Sheldon: The National Science Foundation wants to give me a substantial grant.
Raj: That's a big deal.
Sheldon: I know. When will this nightmare end?

Koothrappali: Oh, great. No Superman, no Wonder Woman? All we've got is a skinny Flash, an Indian Aquaman, a near-sighted Green Lantern, and a teeny, tiny Dark Knight.
Sheldon: Obviously, we're no longer a Justice League. We have no choice but to switch to our Muppet Baby costumes.
Koothrappali: Ooh, I call Kermit.
Sheldon: I'm Kermit. You're Scooter.
Koothrappali: Oh, man. Scooter sucks. He's the Aquaman of the Muppet Babies.

Sheldon: (In Mandarin) Show me your mucus. Your mucus!
Chen: (Mandarin) Blow your own nose and go away!
Sheldon: (Mandarin) This is not a tangerine bicycle. Show me your mucus!
Chen: Crazy man. Call the police.
Sheldon: (Mandarin) No, don't call the library. Show me your mucus.
