Leonard: With all the TV Sheldon was talking about, I had the greatest idea ever. It even blows away my idea for a Star Wars themed coffee shop called Brewbacca's. You need to watch Buffy the Vampire Slayer. It is the perfect show for the two of us. It's got action and jokes and hot vampires and romance. I cannot oversell this. What do you say?
Penny: It's six thirty in the morning.
Leonard: I thought you grew up on a farm.

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, as a scientist, my job is to figure out why things happen. But I don't think I'll ever understand how someone like me could get to be with someone like you. You know maybe I don't need to understand it, I just need to be grateful. I love you, Penny.

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

Sheldon: Well, that stinks. No wonder you got cancelled. Bye.

Amy: Missed one. Now your wish can't come true.
Sheldon: Lucky for you because I wished you were dead.

Sheldon: You don't know what it's like to feel completely frustrated. To have a desire build up within you and be denied any opportunity for release.
Amy: Yeah, sounds like a drag.
