Sheldon: Yeah, I actually have information about Raj that would be helpful with this discussion.
Leonard: Could you tell us?
Sheldon: Let's see. (Rolls dice) Snake eyes. Sorry, bud.
Penny: Wait, hang on. Doubles. Roll again.
Sheldon: Okay, get this. It doesn't matter if he's showering her with gifts, because the Koothrappalis are vastly wealthy.
Penny: What do you mean, vastly wealthy?
Sheldon: Well, wealthy means a lot of money, and vastly means even more. I'm not sure what's tripping you up.

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.

Penny: (Whispers) Here she comes.
Howard: Smart. Whisper so the deaf chick doesn't hear you!

Sheldon: The entrance to the dungeon is a moss covered door. You manage to open it only to find yourself face-to-face with a hideous, foul-smelling, moss-covered ogre. What do you do?
Howard: I say, "Hey Ma, what's for dinner?"

Raj: I don't know if I wanna play any more.
Sheldon: Because you don't have a girlfriend? Well, good lord, if that becomes a reason to not play dungeons and dragons, this game is in serious trouble.
