Leonard: Are you gonna eat that whole pie?
Raj: Maybe. Why not? Who do I have in my life to watch my figure for?
Leonard: Oh, God, did you watch Bridget Jones again?
Raj: No, its just that everybody's got someone. Sheldon's with Amy, Howard's getting married, you're dating my sister.
Leonard: Now that Howard's getting married, maybe he'll inflate one of his old girlfriends for you.

Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
Sheldon: Screwed?
Leonard: There you go.

Leonard: Penny. We are made of particles that have existed since the moment the universe began. I like to think those atoms traveled fourteen billion years through time and space to create us, so that we could be together and make each other whole.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

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.
