Quote from Sheldon in the episode The Jiminy Conjecture

Raj: I don't like bugs, okay. They freak me out.

Quote from Sheldon in the episode The Lizard-Spock Expansion

Quote from Howard in the episode The Tangerine Factor

Howard: You know, I'm really glad you decided to learn Mandarin.

Quote from Stuart in the episode The Hofstadter Isotope

Stuart: Oh, Sheldon, I'm afraid you couldn't be more wrong.
Sheldon: More wrong? Wrong is an absolute state and not subject to gradation.
Stuart: Of course it is. It's a little wrong to say a tomato is a vegetable, it's very wrong to say it's a suspension bridge.

Quote from Sheldon in the episode The Einstein Approximation

Bernadette: Sheldon, when was the last time you got any sleep?

Penny: Toad of truth? Is that a physics thing?
Leonard: No, that's a crazy thing.

Quote from Sheldon in the episode The Alien Parasite Hypothesis

Sheldon: What is the best number? By the way, there's only one correct answer.
Raj: 5,318,008?
Sheldon: Wrong. The best number is 73. [short silence] You're probably wondering why.
Leonard & Howard: No, no, we're good.
Sheldon: 73 is the 21st prime number, its mirror 37 is the 12th and its mirror 21 is the product of multiplying, hang on to your hats, 7 and 3. Did I lie?
Leonard: We get it. 73 is the Chuck Norris of numbers.
Sheldon: Chuck Norris wishes. In binary, 73 is a palindrome, 1001001, which backwards is 1001001, exactly the same. All Chuck Norris gets you backwards is Sirron Kcuhc.
Raj: Just for the record, when you enter 5,318,008 in a calculator, upside down it spells boobies.

Quote from Penny in the episode The Solo Oscillation

Leonard: Thought you were getting us dinner.

Amy: What?
Penny: Yeah, turns out the answer's knots.
Leonard: That's cute, but you can't have knots in more than four dimensions.
Penny: Mmm ... you can if you consider them sheets. [chuckling] Good night.
