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.

Raj: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Doesn't anyone have a rod of resurrection? Because if you've got one, I need it bad. Get in here with your rod and give it to me.
Stuart: Okay, you need to say these things in your head before you say them out loud.

Penny: You know, you compared us to the strangest couple we know, and we know Amy and Sheldon, Howard and Bernadette, Raj and his twitchy little dog.

Amy: How's this for a compromise? Make all the schedules you want, just don't tell me about them.
Sheldon: Excellent. I'll create an algorithm that'll generate a pseudo-random schedule.
Yeah, and do you know why it won't be a true random schedule?
Amy: Because the generation of true random numbers remains an unsolved problem in computer science.
Sheldon: Come with me.
Amy: Where are we going?
Sheldon: To the hotel room. And when we get there, I'm gonna need you to say that again, except naked.

Raj: Sounds like someone's in there.
Bernadette: My God, what if Sheldon and Amy are getting robbed?
Howard: Or worse, what if they're back early?
