Leonard: You will not believe what Stephen Hawking just said.
Penny, Amy and Bernadette: Get out!

Penny: "So instead she asked if in the future Montana ever became a state."
Amy: Hey, in the 1800s that was considered flirting.

Raj: I'm sick of people being mean on the Internet.
Howard: I think the anonymity makes everyone feel like they can say things they'd never say to your face.
Sheldon: Interesting. I can't think of a single thing I wouldn't say to someone's face.
Leonard: Never noticed that about you.

Sheldon: Professor Hawking?
Professor Hawking: Oh, brother. You should see the look on your faces.
Leonard: You really didn't like our paper?
Professor Hawking: I like your paper very much. The premise is intriguing.
Sheldon: Then why are you attacking us?
Professor Hawking: If you were sitting in a chair for forty-years, you'd get bored, too. Anyway, gotta go, I promised to help the neighbor kid with his math homework. Ciao.

Sheldon: Good to see you again, Mr. Stephen Hawking Liked Our Paper.
Leonard: Oh, and you as well, Mr. Our Premise Is Intriguing.
Howard: How do you do, Mr. I'll Admit That's Pretty Cool.
Raj: Yeah, you keep setting me up for failure.

Penny: "With a heavy heart, Amelia stood before the newly repaired time machine. She regretted giving Cooper the part he needed."
Bernadette: Because she wanted him to give her the part she needed.

Leonard: Do you really want him to write back?
Sheldon: I do. And no matter how he responds, I'm going to destroy him with a picture of a bored cat saying "Oh, really?"
Leonard: Mee-wow.

Howard: What are you doing?
Raj: I've created some other user accounts so I can post positive comments about their paper.
Howard: "This wee little bairn of a theory nearly blew my kilt off."
Raj: No, you have to read it like Dr. Angus McDougall of the University of Edinburgh would.
"This wee little bairn of a theory nearly blew my kilt off."

Sheldon: He wrote back! "Cooper and Hofstadter resorting to juvenile attempts at humor is proof they have nothing to back up their ridiculous paper. It should come as no surprise given they work at Cal-Tech, essentially a technical school where even the physicists are basically engineers".
Oh, engineers. Do you know how insulting that is?
Howard: Yes.

Raj: All the other comments said really nice things. Focus on those.
Howard: Yeah. Dr. Dimitri Plankovic of Moscow University said "This paper great. I love it more than vodka."
Raj: See, better with the accent.

Penny: "'Time travel? I don't understand', said Amelia. Cooper stared at her, 'Which word don't you understand? Time or travel."
Bernadette: Wow. Even in your fantasy, Sheldon's kind of exhausting.
Amy: He's like that in the beginning so she can change him. It's called good writing. And wishful thinking.

Sheldon: "My good sir. We are neither crackpots, nor wannabes. In fact, we are experts in our fields. And while you hide behind your anonymity, we stand behind our paper. And later tonight, your mother."
Leonard: You don't think that's too rough?
Sheldon: We're just standing behind her. It's not like we're gonna say "Boo!" and scare her.

Amy: Why? What did I do?
Bernadette: I'm sorry. I had to get the spotlight off me, and tearing down other women is part of my pageant training.

Amy: It's not about me and Sheldon. It's about a young woman in the 1800s named Amelia, and the time-traveling physicist named Cooper she falls in love with.

Penny: "It was just past dawn on the prairie and, like every morning, Amelia prepared to do her chores. Except something about this morning felt different."
Bernadette: Why? Why did it feel different?
Penny: "Maybe it was the first whisper of winter in the air. Or maybe it was the unconscious, handsome man with porcelain skin and curious clothing she was about to discover lying in the field. A man who would open her mind to new possibilities and her body to new feelings."
