Raj: I'm just saying that after everything you've been through, you get to look into each other's eyes and say "I love you." And that's beautiful.
Leonard: Actually, to this day, she's never really said it.
Raj: Oh, Penny. That's ridiculous. You know you love him. You, you look him in the eyes and you say it.
Penny: Raj.
Raj: Oh come on, you know you want to say it. Say it. Say you love him. Say it!

Stuart: A little music?
Raj: Sure. Mmm, bossa nova. You listen to that with your hips as well as your ears.
Stuart: Mmm.
Raj: Oh. Something about Latin music just makes me feel like I'm on a white sand beach in Rio.
Stuart: Yeah. The sun, the waves, the beautiful bodies, tanned and glistening with sweat.
Raj: I should go.

Penny: Ooh, one gravy boat.
Amy: That's from Sheldon. He told me he had it engraved.
Bernadette: In the event of divorce, please return to Sheldon Cooper.
Penny: One inappropriate, yet I wish I thought of that, gravy boat.

Penny: I'm not unhappy at all. It's just, I don't know, I've been in love before, but it felt different. But maybe this is a new, better, boring kind of love. Do you ever feel that way about Howard?
Bernadette: Oh, that's not really a fair comparison. I'm basically married to a sexy Buzz Lightyear.

Penny: Amy, you?
Amy: Can't help ya, kid. Whenever I'm around Sheldon, I feel like my loins are on fire. In the good way. Not the urinary tract infection way.

Howard: You're out of your mind, Sheldon.
Sheldon: That's a negative. My mother had me tested. Over.

Leonard: Sheldon, you are not in charge.
Sheldon: That's mighty sassy for a man with a roommate performance review around the corner.

Sheldon: FYI, secret keeping? Hate it. Hand-holding? Not a fan. Hammerhead shark? I love that thing. Yeah, it's another fish with a tool on its head.

Sheldon: There's something I need to tell you.
Leonard: Okay.
Sheldon: I can't tell you.
Leonard: Why?
Sheldon: I can't tell you why I can't tell you. So I guess there's two things I can't tell you.
Leonard: I wish there were more.

Leonard: Okay, I think I understand.
Sheldon: You do?
Leonard: The guy who seems like an emotionless robot is you, but your relationship with Amy is causing you to transform into a red-blooded man with sexual desires.
Sheldon: That is literally the stupidest thing I've ever heard.

Sheldon: Leonard, maybe you'd like to go with them to meet girls.
Leonard: Why would I be interested? I have Penny.
Sheldon: Yeah, for now. But that woman has a death wish, Leonard. She talks to strangers, she pets unfamiliar dogs, and it is ridiculously easy to break into her apartment. If I were you, I'd get a back-up.

Amy: You slept with him?
Penny: I didn't know what else to do. He had those big, sad eyes.
Bernadette: Oh, sure, you had no choice.

Sheldon: Okay, my turn. Let me talk to him.
Leonard: Go ahead.
Sheldon: 2311 North Los Robles Avenue, Pasadena, California to International Space Station. Can you read me? Over. (Makes static noise)
Howard: Yes, I read you, Sheldon.
Sheldon: Copy that. Over. (Static)
Leonard: What are you doing?
Sheldon: I am talking to a man in space. If you don't have the (static) then he might as well be at the Coffee Bean over on Lake Street.
Howard: You're out of your mind, Sheldon!
Sheldon: That's a negative. My mother had me tested. Over.

Raj: What's the big deal? You guys are bringing your girlfriends. I didn't want to sit by myself.
Sheldon: The big deal is I was expecting us to be an intimate group of five. Now, we're going to be a faceless mass of six.

Leonard: It'll be fine. Just, uh, pretend he's Wolowitz.
Sheldon: Hmm. Do you like Raisinets?
Stuart: I can take them or leave them.
Sheldon: At the movies, Wolowitz always eats Raisinets.
Stuart: Would you feel more comfortable if I ate Raisinets?
Sheldon: Well, it's hardly my business what you eat. As long as it doesn't crunch during the film and it's Raisinets.
