Leonard Hofstadter : I thought we were in the kind of relationship where we make decisions together. If I'm wrong, maybe we should talk about the kind of relationship we are in.
Penny : Yeah, well, maybe we do.
Sheldon Cooper : I'm willing if you guys are.
Leonard Hofstadter : Can we please have some privacy?
Sheldon Cooper : No, I'm as much a part of this relationship as you two. I think that it is high time that we put all our cards on the table. For example, where is this going? Are you two ever getting married? And if so, where will we all live? Have you thought about that?
Leonard Hofstadter : No.
Sheldon Cooper : Penny?
Penny : Okay, wait. What are we doing?
Leonard Hofstadter : For some reason, we're planning a future where we both live with Sheldon forever.
Penny : Look, I know you think I am being reckless, and you might be right, but I need to take this shot
Sheldon Cooper : Yeah, no kidding. Despite what it says on her resume she is no longer 22.
Leonard Hofstadter : I swear, I am on your side.
Penny : You keep saying you're on my side, but you don't act like it.
Sheldon Cooper : He does that to me too. Why do we put up with this?
Leonard Hofstadter : Listen. I could never do what you are doing, okay? I would be terrified.
Penny : Well, it's scary for me too.
Sheldon Cooper : I'm fine with it.
Leonard Hofstadter : My point is, just because I couldn't do it doesn't mean you shouldn't. And I'm proud of you.
Penny : Okay. Thank you.
Man V.O. : Close your eyes and imagine yourself in a peaceful place.
Sheldon Cooper : All right. I'm at the Hadron Supercollider.
Man V.O. : Now breathe in...
Man V.O. : ... and out.
Sheldon Cooper : Wow. Didn't see that coming.
Man V.O. : Once again. In...
Sheldon Cooper : [Inhales] Let me guess.
Man V.O. : ...and out.
Sheldon Cooper : What was I going to do, two ins in a row?
