Quotes 

• Leonard Hofstadter : So, Amy, what's going on with your addiction study?

  Amy Farrah Fowler : Sadly, I'm no longer associated with that project.

  Leonard Hofstadter : Why? What happened?

  Amy Farrah Fowler : Typical bureaucratic nonsense. You can get animals addicted to a harmful substance, you can dissect their brains, but you throw their own feces back at them, and suddenly you're unprofessional.

  Leonard Hofstadter : I'm sorry... that I asked.

• Howard Wolowitz : I'm telling you, something's wrong. I can always feel it when Raj is in trouble.

  Bernadette Rostenkowski : Jeez. How close were you guys before we got married?

  Leonard Hofstadter : Don't look under that rock.

• [last lines] 

  Penny : [Penny is performing on stage in A Streetcar Named Desire as Blanche DuBois]  You love her very much, don't you?

  Tom : Yes.

  Penny : I think you have great capacity for devotion. You'll be lonely when she passes on, won't you? I understand what that is.

  Tom : To be lonely?

  Leonard Hofstadter : She's pretty good, huh?

  Sheldon Cooper : She is, but when do they get to the part about streetcars?

  Penny : ...when I was a very young girl. When I was sixteen years old I made the discovery. Love. All at once and much, much too completely. It was like you suddenly turned a blinding light on something that had always been half a shadow. That's how it struck the world for me. But I was unlucky. Deluded.

  Sheldon Cooper : She's remarkable.

  Leonard Hofstadter : She really is.

  Amy Farrah Fowler : Our Penny's a star.

  Sheldon Cooper : How can she remember all those lines, but as a waitress she can't remember "no tomato" on my hamburger?
