Sheldon: I'm just worried that if I don't schedule our bedroom endeavors, then I may not think about them, and you'll grow cold and distant and seek solace in the arms of a heavily-muscled longshoreman.
Amy: Where would I find a longshoreman?
Sheldon: Along the shore. It's in the name.

Amy: Sheldon, I could never be with anybody but you.
Sheldon: That's good to know. I wouldn't want to fight a man who's brave enough to touch a fish.

Dr. Neil deGrasse Tyson: Well, that was fun. Let's see who else needs a deGrasse kickin'.
Bill Nye: Bill Nye the Science Guy.
Dr. Neil deGrasse Tyson: Hey, Bill, Neil Tyson. We've got to talk.
*Bill Nye quickly hangs up the phone*

Penny: Well, 30 years from now, are you gonna hide from me because I'm so scary?
Leonard: Hey, I don't think you're scary. Yes, I flinch when you make sudden moves, but that says more about my childhood than you.
Penny: Aw.
*Penny goes to huge Leonard, he flinches and backs away. He recovers and hugs her.*

Raj: Go for Dr. K.
Dr. Neil deGrasse Tyson: Is this Rajesh Koothrappali?
Raj: Yes. Who is this?
Dr. Neil deGrasse Tyson: Neil deGrasse Tyson.
Raj: (stammers) Uh, wow. (chuckles) How fun is this Twitter thing, huh?
Dr. Neil deGrasse Tyson: You think you're funny?
Raj: I'm not Seinfeld funny, but I did an open mic night once.
Dr. Neil deGrasse Tyson: You're not funny.
Raj: Yeah, that's what they said at the Chuckle Hut.
Dr. Neil deGrasse Tyson: How about this, I've got a book signing at Vroman's in Pasadena next week. Why don't you come by and say some of those things to my face?
Raj: (chuckles) Oh, no, but thanks for the invite.
Dr. Neil deGrasse Tyson: Smart move, and the next time you pick up your phone, remember, I'm the guy who kicked Pluto out of the solar system.
Raj: And it deserved it, sir. Thank you. Bye-bye.

Sheldon: Oh, I almost forgot. While you were sleeping, I ordered room service.
Amy: Really?
Sheldon: Voila! You thought it was going to be food, didn't you?

Raj: Is it nice having Sheldon and Amy away on their honeymoon?
Penny: Yeah, because now Leonard and I get all this alone time.
Raj: But you're not alone. We're here.
Penny: Yes. (sighs) Yes, you are.
Bernadette: Would you like us to leave so you and Leonard can talk about all the things you have in common?
Leonard: Ha, ha, she called your bluff.

Raj: So, something pretty cool happened. Channel 3 asked me to be on the news tomorrow night to talk about the meteor shower.
Leonard: Oh, that's great.
Penny: Hey-
Bernadette: Congratulations.
Howard: You know, that's how Neil deGrasse Tyson got his start. He went from the Hayden Planetarium to guesting on the local news to ruining everyone's favorite movies on the Internet.

Leonard: They're not; they just posted a picture in front of the Statue of Liberty.
Penny: Real or Lego?
Leonard: Lego.

Bernadette: So, what should we do? Should someone go check it out?
Raj: I would, but I got to be on TV tomorrow. Got to protect the money.

Penny: Oh, uh, Mr. Fowler. Sorry, we didn't know you were here. We actually thought someone was breaking in.
Raj: And we were ready to take them down.
Mr. Fowler: Amy asked me to water her plants.
Penny: She doesn't have any plants.
Mr. Fowler: Oh. Well, you caught me in a lie. Have a good day.

Penny: Hey, did you even see Mamma Mia 1?
Leonard: Didn't need to. The sequel stands on its own.

Bellman: If you need any recommendations while visiting New York, please don't hesitate to contact me.
Amy: Well, it is our honeymoon.
Sheldon: So we are going to be quite busy.
Bellman: Got it.
Amy: Harry Potter play, parts one and two.
Sheldon: And tomorrow, a tour of the sites where Nikola Tesla lived, worked and slowly went crazy. And, of course, coitus.
Bellman: Ah. Well, enjoy New York. And, I guess, coitus.

Mrs. Fowler: Larry, come on.
Leonard: I don't think he's in there. I mean, he came by to water the imaginary plants, but then he left.
Mrs. Fowler: You are so naive. Blondie here is gonna chew you up and spit you out.
Penny: Well, don't tell him.

Mrs. Fowler: Oh, he's in here. I can smell his Axe body spray.
Leonard: He wears Axe body spray.
Penny: You happy? You smell like Amy's dad.
