Denise: Do you think when Krypto the Superdog is out flying, Superman has to fly after him with a little baggie?
Stuart: Hmm. Haven't really thought about it before. But he doesn't need a baggie, because he just blasts the poop with his heat vision.
Denise: You've thought about it before.
Stuart: Oh, I've thought about it a lot.

Stuart: Seriously, do you think I should ask her out?
Raj: Absolutely. Don't let love get away. It is the most important thing in the world. Without it, life is dark and meaningless and all you're left with is the judgmental gaze of your dog as you finish off a bag of Doritos on the toilet.

Amy: I can't stop thinking about that present. It's driving me crazy.
Sheldon: Me, too! The card said it was the perfect gift. But it's not a dinosaur fossil or matching pocket watches, so I don't see how it can be.

Sheldon: We just need to think like them. (inhales, exhales) Okay. What gift can I get us to express how grateful we are to have us in their lives?
Amy: Way to make it simple.

Bernadette: What's wrong with his face?
Howard: A lot of people have been asking that. He's smiling.
Bernadette: Hey, Stuart, you look pretty happy.
Stuart: Oh, yeah. I, uh, asked Denise out on a date, and she said yes.
Bernadette: Aw. That's great. But don't smile like that in front of Halley. She just started sleeping through the night.

Stuart: I'm excited. I haven't been on a date in a long time.
Howard: Back when I was dating, I'd always wear a new pair of underwear, just in case.
Stuart: It's also been a long time since I bought new underwear. And I probably should, because these are no longer tighty nor whitey.
Bernadette: Okay, I'm out.

Sheldon: I just wanted to pop over and hand-deliver this thank you note for your very thoughtful wedding gift.
Penny: Oh.
Leonard: Oh, good. You guys liked it?
Sheldon: Well, we liked it a lot more than things that aren't it, I'll tell you that.
Penny: Well, yeah, that's great. Because when we saw it, we thought, "Amy and Sheldon just have to have that."
Sheldon: Oh, do tell. Now, paint a picture for me, like where you were when you found it and what you thought we'd enjoy doing with it.
Leonard: Do you not know what it is?
Penny: Of course he knows what it is. He's the smartest man in the world.
Sheldon: Well, I don't know about the world. Some of those Chinese fellas are pretty clever. Now, if you'll excuse me, I'm going to return home and use your gift in the manner which it was intended.

Raj: Well, what is it? What did you give them?
Leonard: Oh, i-it's just this dumb crystal wand that Howard and Bernadette gave us for our wedding. Penny and I made each other miserable trying to figure out what it was, and we thought, "Why not pass that fun along to Sheldon and Amy."
Raj: Wait a minute. Did-- did you give them the crystal chakra wand that I gave you for your wedding?
Howard: Yeah, that's exactly what we did.
Raj: You said you liked it!
Howard: Yeah, that's exactly what I said.

Amy: So, do you know what it is?
Bert: Of course I know what it is. It's a silicon dioxide crystal, otherwise known as quartz.
Sheldon: Are you sure?
Bert: Am I sure? Is basalt a mafic extrusive igneous rock formed by the rapid cooling of magnesium and iron-rich lava? Yeah, I'm sure.

Amy: Okay, so it's quartz. That's got to mean something. What do we know about quartz?
Sheldon: I'll Google it.
Bert: Or you can ask me, the geologist who won the MacArthur Genius Grant.
Sheldon: Got it!

Sheldon: Quartz, from the German "quarz" which sounds the same, but is spelled without a "T".
Amy: Interesting. No "T". What is not "T"?
Sheldon: Coffee!
Amy: The coffee shop where we first met!
Bert: All right, let's go. Sorry. I think I just had an adrenaline rush from having visitors.

Stuart: I'm trying out some new colognes for my date with Denise.
Raj: Oh, and you just came over here to rub it in my face that you have a date?
Stuart: No. I came over here because I need advice, and you've gone out with more women than anybody I know.
Raj: Huh. I guess you're right. Sheldon's the smart one, Howard's the funny one, and apparently, I'm the ladies' man.
Stuart: Which one's Leonard?
Raj: Oh, yeah, right. I guess Leonard's the forgettable one.

Sheldon: I met my wife here, and we sat at this very table, so if you play your cards right, in eight years, you could marry this woman.
Greg: That's my sister.
Sheldon: Well, don't tell people. That's not okay.

Howard: Oh. Look what Halley drew.
Bernadette: Yeah, she made it at daycare.
Howard: It's pretty good, huh?
Bernadette: Is it?
Howard: Wow. Gentile moms are tough.

Stuart: I'm picking her up in an hour. What am I gonna do?!
Howard: Don't you mean what are you gonna "Oompa Loompa doompety do"?
