    • Howard: I want you to tell me I'm good at what I do.
      Sheldon: You're obviously good at what you do.
      Howard: Then why are you always ripping on me?
      Sheldon: Oh, I understand the confusion. I have never said that you are not good at what you do; it's just that what you do is not worth doing.

    • Penny: Why are you washing Howard's man-panties?
      Sheldon: 'Cause if I don't he won't give my paper to Stephen Hawking. He's a famous physicist—
      Penny: Yeah, yeah, I know. He's the wheelchair dude who invented time.
      Sheldon: Close enough.

    • Penny: I see that twinkle in your eye when someone says "who" instead of "whom" or thinks the moon is a planet.
      Sheldon: Or Don Quixote is about a donkey named Hotay.

    • Sheldon : Oh, gosh golly. I made a boo-boo. And I gave it to Stephen Hawking. (Passes out)
      Stephen Hawking: Great. Another fainter.

    • Sheldon: Now will you give my paper to Hawking?
      Howard : Sorry, I can't.
      Sheldon : Why not?
      Howard : I gave it to him three days ago. He was really impressed. Wants to meet you.
      Sheldon : All right then. Thank you, Howard. Please let Professor Hawking know I am available at his earliest conveniences. (Walks out of the room)
      Raj: Thought he'd be a little more excited.
      Leonard : Give it a second.
      Sheldon : WAA-WAA-HOO!
