Raj: I don't know which Hemsworth is playing Logan Dean, but I know it's a Hemsworth.
Leonard: Well, Logan's actually based on me.
Raj: So a young Paul Giamatti.

Amy: Well, what if I watch it with you? Maybe I won't like it and we can complain about it together.
Sheldon: Get your own thing to complain about.
Amy: Oh, trust me, I've got one.

Howard: Hey, Professor Proton.
Wil Wheaton: Hey, thanks for being here.
Howard: No problem. I'm on my "launch" break.

Leonard: And then, when the lights come back on in the supercollider room, Dr. Logan Dean makes two important discoveries, gluino (gruffly) and murder.
Howard: Oh, gluino. That's exciting.
Leonard: (gruffly) And murder.
Howard: (gruffly) I heard you. The first time.

Bernadette: So, does Penny know you based a character on her?
Leonard: What character?
Bernadette: Ilsa, the head of the institute. That's clearly Penny.
Leonard: No, it's not.
Bernadette: Really? Confident, ball-busting beauty who's always rolling her eyes at Logan?
Leonard: Trust me, that describes more women than you think.

Sheldon: Wil Wheaton wants you to be on Professor Proton.
Amy: That's nice, but I'm not really interested.
Sheldon: What do you mean? But he wants to talk about women in science. You're a woman, you're in science. You go, girl.

Bernadette: Boy, I don't know how people who aren't on bed rest keep up with the Kardashians.
Penny: Well, sometimes you have to read in your car while your husband thinks you're working late.

Sheldon: I just learned some very distressing news. Sometimes, Amy doesn't do things because she's worried about how I'll react.
Howard: First of all, it's not sometimes, it's always.
Raj: Second, it's not Amy, it's everybody.
Howard: And third, it's not news, it's well-established.

Raj: Yeah. Like just now I wanted to get a croissant, but I didn't want to hear you say, "Ooh, la, la."

Sheldon: So you're saying everyone walks on eggshells to spare my feelings?
Howard: No, of course not, because we don't want to hear you complain about how much you hate the sound of crunching eggshells.

Sheldon: Well, regardless, I can change.
Howard: Sure.
Raj: Yeah, of course you can.
Sheldon: You know, everybody thinks I'm so predictable. Well, tomorrow I'm gonna show up at work and do something no one will expect.
Howard: Wear a baseball cap backwards to prove your point?
Sheldon: ... Yes, but which hat?
Raj: Gryffindor.
Sheldon: Well, now that you guessed it, I'm not gonna do it.
Raj: Yeah, you will.
Sheldon: Yeah.

Sheldon: I'm sorry. It's, I'm trying to show you that I can change. I don't want you to miss out on things because of me.
Amy: I know you don't.
Sheldon: You know, and maybe somewhere out there, there is a little girl who will see you on Wil's show and realize that she, too, can grow up to be a brilliant, amazing, successful scientist.
Amy: Thank you.
Sheldon: Who is really terrible at chess.
Amy: Got it.
Sheldon: No, no, no. I mean really bad. What was your queen doing over there, going shopping?

Sheldon: So you're not going to do something just because you think it might upset me?
Amy: Well, it's tricky, because answering that question honestly is one of the things I tend not to do because it upsets you.
Sheldon: Well, that's very upsetting.
Amy: Like I said.

Sheldon: What other things don't you do because of me?
Amy: Remember last week when we went to that dueling piano bar I was so excited about?
Sheldon: No.
Amy: Well, now you're getting it.

Amy: Look, at least if you watch it, maybe you can find more specific things to criticize.
Sheldon: Oh, that is a good point. Criticisms are more hurtful when they're specific.
