Sheldon: How shall we begin?
Penny: Well, I thought we'd start with some basic movement exercises. You know, get our bodies warmed up a little.
Sheldon: All right.
Penny: So I just want you to relax and kind of move around in the space. You know, just do whatever feels natural. Sheldon?
Sheldon: (standing still) You said to do whatever feels natural. This feels natural. Certainly more natural than what you're doing.
Penny: Come on, you got to work with me. We need to get connected with our bodies.
Sheldon: Penny, my body and I have a relationship that works best when we maintain a cool, wary distance from each other.

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.

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.

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.

Raj: Dance number aside, I'm so not gay.

Penny: Mrs. Cooper? Hey, it's Penny. I think I broke your son. Hold on. Talk to your mother.
Sheldon: (Crying) Mommy, I love you. Don't let Spock take me to the future!

Raj: I know the feeling. It's like accidentally walking into a gay bar and then having no one hit on you. It happened to a friend of mine.
