Quotes 

• Leonard Hofstadter : 210, and you throw in the Iron Man helmet.

  Stuart : Are you crazy? That helmet's signed by Robert Downey Jr.

  Leonard Hofstadter : So?

  Stuart : Okay, if you're gonna question the importance of an actor's signature on a plastic helmet from a movie based on a comic book, then all of our lives have no meaning!

• Leonard Hofstadter : Okay, Sheldon, we're going to Wil's. This is your last chance!

  Sheldon Cooper : No, Leonard, this is your last chance. One day, a historian is going to come to you and say: "Is it true you were friends with Dr. Sheldon Cooper?" And you're going to have to choke back a hot sob of regret and humiliation as you mumble, "I was, but I chose to go to a party thrown by the one kid from 'Stand By Me' that no one remembers."

• Sheldon Cooper : If we were starting a sword collection, I would start with Excalibur. You could rule England with it.

  Leonard Hofstadter : It would be a plastic replica of a movie prop.

  Sheldon Cooper : You could rule a replica of England with it.

• Stuart : [negotiating with Leonard and Sheldon for a sword]  225. That's my final offer.

  Sheldon Cooper : [to Leonard]  Take it, take it, take it!

  Leonard Hofstadter : 200.

  Stuart : Man, you're killing me!

  Sheldon Cooper : Killing you? I can't breathe!

• Leonard Hofstadter : Will you stop with the Schrödinger stuff?

  Sheldon : Would you prefer a simpler application of Heisenberg's uncertainty principle? In which I could either know where you are, or whether I like you, but not both?

  Leonard Hofstadter : You never stop talking, do you?

  Amy Farrah Fowler : I don't understand, what difference does it make if Leonard goes to Wil Wheaton's party?

  Penny : Wil Wheaton is Sheldon's mortal enemy.

  Amy Farrah Fowler : Sheldon, I know you're a bit of a left-handed monkey wrench but you really have a mortal enemy?

  Sheldon : In fact, I have 61 of them. Would you like to see the list?

  Penny : Oh, say no, say no, say no, say no.

  Sheldon : [to Penny]  You just got off the list. Would you like back on it?

• Leonard Hofstadter : You actually asked Bernadette to leave your house in the middle if the night?

  Howard Wolowitz : What choice did I have? She went behind my back and turned my own mother against me.

  Raj Koothrappali : Wow, you're not only our first astronaut, you're also the first one of us to kick a girl out of bed.
