Popular Quotes
Quote from Sheldon in the episode The Jiminy Conjecture
Raj: I don't like bugs, okay. They freak me out.
Sheldon: Interesting. You're afraid of insects and women. Ladybugs must render you catatonic.
Quote from Sheldon in the episode The Lizard-Spock Expansion
Sheldon: Scissors cuts paper, paper covers rock, rock crushes lizard, lizard poisons Spock, Spock smashes scissors, scissors decapitates lizard, lizard eats paper, paper disproves Spock, Spock vaporizes rock, and as it always has, rock crushes scissors.
Quote from Howard in the episode The Tangerine Factor
Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.
Quote from Sheldon in the episode The Gorilla Experiment
Sheldon: Why are you crying?
Penny: Because I'm stupid.
Sheldon: That's no reason to cry. One cries because one is sad. For example, I cry because others are stupid, and that makes me sad.

Quote from Sheldon in the episode The Contractual Obligation Implementation
Leonard: So now let's bring out theoretical physicist, Dr, Sheldon Cooper.
Sheldon: Hello, female children. Allow me to inspire you with a story about a great female scientist. Polish-born, French-educated Madame Curie. Co-discover of radioactivity. She was a hero of science until her hair fell out, her vomit and stool became filled with blood, and she was poisoned to death by her own discovery. With a little hard work, I see no reason why that can't also happen to any of you. Are we done? Can we go?
Quote from Raj in the episode The Convergence Convergence
Howard: I'm just afraid if I respond, then they'll know I got it.
Raj: Oh, dude. The minute you opened that e-mail, they knew you got it. I mean, they're probably looking at you through the camera right now. (Howard closes the laptop, Raj re-opens it and looks at the camera) I love America!
Quote from Sheldon in the episode The Einstein Approximation
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.
Quote from Sheldon in the episode The Shiny Trinket Maneuver
Penny: Sheldon, what is wrong with you?
Sheldon: Not much. Although, I can be faulted for being overly fond of koala bears. I don't know what it is, but when they start munching on eucalyptus, I just melt inside.
