Howard: My name is Inigo Montoya. You killed my father. Prepare to die.

Raj: My name is Little Orphan Annie. You killed my father. Prepare to die.
Howard: My name is Darth Vader. I am your father. Prepare to die.

Bernadette: Stuart took that rejection like a pro.
Penny: Well, he knew he was on the breast cam.
Amy: I don't have much practice turning men down. It wasn't so much fun.
Bernadette: Oh, you get used to it. Some guys you have to turn down over and over.
Penny: And sometimes we marry them anyway.

Sheldon: Excuse me, Barry?
Barry Kripke: Yes?
Sheldon: When can I stab one of my friends?
Barry Kripke: In fencing, we don't call it a stab. We call it a touch.
Sheldon: Uh, yes, I'm aware. But if I say I want to touch one of my friends, I'll get called into Human Resources.

Sheldon: According to a recent study, simply thinking about exercise, even while sitting still, can have physical benefits. For all you know, I could be exercising right now.
Raj: Are you?
Sheldon: Na, I'll do it tomorrow.

Sheldon: Barry Kripke was there. I should let you know that he expressed interest in asking you out.
Amy: Well, actually, he already did.
Sheldon: Okay. But don't get too attached to him. In two years, 364 days, he's a dead man.

Penny: I think it's great you guys want to get more exercise, but do you really think sports is the right choice for you?
Leonard: What are you saying? We're not coordinated enough to play sports?
Penny: Okay, Leonard, sweetheart, you twisted your ankle playing Scrabble.
Leonard: I got a triple-word score with a double letter Q. If that's not a time to bust out the Scrabble dance, what's the point of having one?

Penny: Uh, have you read the online reviews for this place?
Stuart: Eh, the Internet's so negative. I try to avoid it.
Penny: All right. Well, Heather H. says, "The owner stared at me the whole time and didn't blink once."
Kelly M. says, "The creepy guy who runs it asked me out, then called himself stupid before I could say no."
Jessica K. says, "I told the weird owner that I liked his shirt. He took it off and gave it to me."
Stuart: See? Negative.

Sheldon: En garde, Leonard. Prepare yourself for a rigorous touching.

Leonard: Look, even if it's not him, Amy's probably going to date someone at some point.
Sheldon: You really think so?
Leonard: Of course. She deserves to be happy.
Sheldon: How dare you!

Howard: Sheldon, instead of focusing on Amy dating other guys, maybe you should start thinking about dating another girl.
Sheldon: That's ridiculous.
Raj: Why? You never thought you'd end up in a relationship, and then you met Amy. Maybe there's someone else out there for you.
Sheldon: True, but Penny's married, and so is Bernadette. And your girlfriend has red hair and white skin, which really rubs up against my clown phobia.

Sheldon: Excuse me. I'm recovering from a recent breakup, and I'm told asking out another woman might make me feel better.
And as Ash Ketchum said to Pikachu, "I choose you."
Woman: What?
Sheldon: It's a Pokemon reference.
Woman: I don't know what that means.
Sheldon: Well, we gave it a shot.

Leonard: Hey, ready for lunch?
Howard: Oh, one sec.
Sheldon: Is that the prototype drive system for the high-G rover?
Howard: No, Bernadette got me a Fitbit so she can track how much I'm exercising.
Leonard: That'll teach her to care about your health.
Howard: Yeah, I can't wait to see the look on her face when I die young.

Raj: When was the last actual exercise you got?
Howard: The other day when she tried to put that Fitbit on me and I ran away from her.

Sheldon: And as an added bonus, the word touche comes from fencing. It would be our only opportunity to use it in a non-metaphorical sense.
Leonard: What about a game of tag on a French school yard?
Sheldon: Ah, touche.
