Leonard: How was your day?
Penny: Oh, not good. Still couldn't get in to see Dr. Gallo.
Sheldon: A doctor? Well, I hope you're not contagious. I've got a weekend in the telescope room I've been excited about for almost three minutes.

Stuart: Hmm. (looking around at the room)
Howard: What?
Stuart: I just have never been in this room while you're awake.

Sheldon: Well, I can be helpful. Give me something to do. You know, my father took me to work once, and in ten minutes I figured out who'd been stealing from the cash register.
It was my father. Yeah, Dad lost his job, but Mr. Hinckley gave me a Fudgsicle.

Leonard: Thank you for seeing me on such short notice.
Dr. Gallo: Ah, it's my pleasure. I'm curious, are you related to Dr. Beverly Hofstadter?
Leonard: Uh, she's my mother. You know her?
Dr. Gallo: No, not personally, but I have read all of her books.
Leonard: Well, then you know her better than I do.
Dr. Gallo: Well, I'm not so sure about that. But I can tell you I do not agree with her theories on child rearing at all.
Leonard: Really? Any chance you find them cold, cruel and unsuitable for innocent little boys who just want to be happy?
Dr. Gallo: Well, I didn't want to say it-
Leonard: No, no, say it. Sing it. Rent a plane, write it in the sky.

Leonard: All right, well, after we talked about my issues with my mother - nothing too deep, just how she ruined my life - I told her about you and your drug; she said she'd be happy to meet you.
Penny: Really? Oh, you're the best husband ever!
Leonard: So you'll go to the Doctor Who convention with me next week?
Penny: I guess.
Leonard: Oh, I actually did hear your eyes roll that time.

Sheldon: Oh, Leonard, great news. We discovered a medium-sized asteroid together.
Leonard: Wow, that's amazing! I'm in a pretty great mood today myself.
Sheldon: Okay. Guess we're gonna talk about you now.
Leonard: Well, we are, because Dr. Gallo made me realize that I'm a worthwhile person and that my feelings matter.
Raj: I learned that for free from a cat poster, but good for you.

Raj: So I was thinking, maybe we can come up with a name for the asteroid by combining our names.
Sheldon: That's a great idea. I've got it. We'll call it "Cooper".
Raj: How is that both our names?
Sheldon: "Koo" from Koothrappali and "per" from Cooper.
Raj: Yeah, so it's, like, "Kooper" with a "K"?
Sheldon: Nah, you're right, that's dumb.

Stuart: Boy, who would've thought when you asked me to move in and help take care of your mom, I'd still be here two years later?
Howard: No one.
Bernadette: Nobody thought that.

Amy: Hi, Sheldon. What's up?
Sheldon: Good news. You're an asteroid.
Amy: Uh, please tell me what to say next.

Raj: And you know we get to name it.
Sheldon: We better choose a name no one can make fun of. Sir Frederick William Herschel didn't do Uranus any favors.

Howard: What is happening? Are we missing him?
Bernadette: No, that's not what this feeling is. Is it?
Howard: Of course not. He drove us crazy. Like when you were gonna make that pie and Stuart ate all the blueberries.
Bernadette: And he tried to deny it, but his teeth were all purple.
Howard: That was pretty cute.
Bernadette: Yeah. Eww, we are missing him!

Howard: Bernie and I are getting the house ready for the remodel. We could always use an extra pair of hands.
Sheldon: That sounds awful. Raj?
Raj: Uh, I've got time booked in the telescope room all weekend scanning for rogue planets. You're more than welcome to join me.
Sheldon: That's the one to beat, Leonard.
Leonard: Oh, if anything, I'm trying to get my Sheld-off.

Sheldon: What are you doing?
Raj: Uh, making sure the telescope's camera is white-field balanced.
Sheldon: Hmm. What are you doing now?
Raj: Still making sure the telescope's camera is white-field balanced.
Sheldon: Oh, I see. How about now?
Raj: Now I'm making sure the telescope's camera is white-field balanced and wishing you had a coloring book.

Raj: Fine, you want something to do? There's about six months of data on this hard drive.
Why don't you go through it and see if you can spot any patterns or anomalies.
Sheldon: Yep, I'm on it. Hey, look at that! An Indian guy outsourcing a computer job to a white fella.

Bernadette: Oh, look. The teddy bear Stuart won the night we took him to the fair.
Howard: Oh, he was so excited.
Bernadette: Yeah. You know, no matter how hard they tried, they could not guess his age.
