Sheldon Cooper quotes

“While I subscribe to the many-worlds theory which posits the existence of an infinite number of Sheldons in an infinite number of universes – I assure you that in none of them am I dancing.”

“Oh, on the contrary. I found The Grinch to be a relatable, engaging character, and I was really with him right up to the point that he succumbed to social convention and returned the presents and saved Christmas. What a buzzkill that was.”

“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.”
