How could you let him go?!

Amy

Leonard: Sheldon...
Sheldon: Yes?
Leonard: I'm gonna miss you.
Sheldon: Of course you are.
Leonard: He just made that easier.

Penny: He'll be okay. You taught him well, Padawan.
Sheldon: Good Lord! Padawan's the student,
not the teacher.
Penny: Seriously, let him go.

Leonard: So a few things don't go your way and your best decision is to ride the rails like a hobo?
Sheldon: I suppose it is. Except I have a credit card. And I refuse to carry my laptop at the end of a stick. And I'd sooner die than eat beans out of a can.

Leonard: I know his password, so I can track his phone.
Penny: You do that?
Leonard: Not always, but ever since he wandered off at the swap meet chasing a balloon, I get worried.
Penny: He can take care of himself. Look, we went over stranger danger and gave him that whistle.

I do not accept this. Everything is changing and I hate it. It stops now.

Sheldon

Amy: Maybe you'll love living alone.
Sheldon: I don't know. Perhaps.
Amy: And if it turns out you don't ... you and I could live together.
Sheldon: You and... Oh, sure. And while we're at it, why don't we get engaged, too? Why don't we get a little house, start a family? Enjoy our sunset years together? Do you hear yourself, woman?!
Amy: Sheldon, it was just a thought.
Sheldon: No. Here's a thought. You're not moving in, Leonard's not moving out, everything stays exactly the way it is.

Sheldon: Move across the hall?! Did you take a marijuana?!
Leonard: No, I did not.
Sheldon: Did you get hit on the head with a coconut?
Leonard: No.
Sheldon: Well, then, I'm all out of guesses.

Sheldon: She's spent many nights here, and you're worried about preserving the myth of her virginity before the wedding.
Leonard: I'm not.
Sheldon: Good, because not only has that ship sailed, if it hit an iceberg, countless men would perish.

Leonard's Mom: Leonard, would it make you feel better to hear that your mother approved of your life choices?
Leonard: Yes, it would.
Leonard's Mom: Yeah. Well, you should work on that.

Howie, I love you,and as your wife, your mother is every bit as much my problem as she is yours, so ... I want a divorce.

Bernadette

Raj: Boy, I'm so hungry today. I wonder why?
Howard: Because you had sex the other night?
Raj: You know what? That may be it. By the way, it isn't like riding a bike. Like, I fell off a few times.

Howard: There's a party for incoming post-docs tonight. Go to it and meet someone who isn't made of grease or pie.
Raj: You think you're so cool because your wife is a person?

Sheldon: Even the dung beetle chooses to plot its course by using the Milky Way.
Raj: Is that true?
Sheldon: Everything I say is true. Now, of course, the dung beetle also enjoys eating fece, living in feces and making little balls out of feces. So, pick and choose which aspects of its lifestyle you want to embrace.
