Bernadette: I guess we could give it a try.
Sheldon: Well, little lady, you've heard of party hearty, get ready to party hardly.

Leonard: The difference is she's bringing life into the world, and you suck it out.

Penny: Oh, hey, if you guys are free this weekend, I won a night of wine tasting from work.
Leonard: That sounds fun.
Leonard: How come scientists don't win free stuff like salespeople do?
Howard: 'Cause we're not in it for the stuff. (Puts his arm around Bernadette) We're in it for the groupies.

Amy: Well, it sounds like a nice night. We should go.
Sheldon: Wine again? Yeah, no, thank you. I like my grapes the old-fashioned way, in a juice box.

Sheldon: Personally, I find the notion of external rewards demeaning. I pursue science for the intrinsic joy of discovery.
Amy: But you always say that you want to win a Nobel Prize.
Sheldon: I also say don't contradict me in front of my friends, but that you don't remember.

Penny: All right, well, let me know if you guys want to go.
Raj: I would love to. I do enjoy the complexity of an aged Pinot noir.
Leonard: I'm sure that would pair nicely with your fried nuggets of chicken.

Amy: Well, I'm going. You couldn't stop me from getting a massage at the mall, and you're not stopping me now.
Sheldon: I shouldn't have to see my girlfriend get groped in public by another man.
Amy: And I shouldn't have to see my boyfriend riding on a train for children around the mall.
Penny: The little choo-choo for toddlers?
Amy: And now you know why I needed the massage.

Sheldon: *Knock, knock, knock* Leonard. *Knock, knock, knock* Leonard. *Knock, knock, knock* Leonard.
Leonard: What?
Sheldon: I never got to ask my question about Batman.
Leonard: What is it?
Sheldon: If Batman were bitten by a radioactive Man-Bat, and then fought crime disguised as Man-Bat, would he be Man-Bat-Man-Bat-Man or simply Man-Bat-Man-Bat-Batman?
Penny: Is he still wearing the Batman suit under the Man-Bat suit?
Sheldon: (a moment's pause) I'll be back.

Amy: That was scary.
Sheldon: Well, the important thing is I said that big sandwich would ruin everything, and I was right.

Raj (shouting from upstairs window): Hey, Jon Snow. How come your horse has a basket on it?
Stuart: How come your head has your face on it?
Sheldon: They don't wear bicycle helmets in Game of Thrones. You're thematically inaccurate, but I applaud your commitment to safety.
Stuart: Don't you guys have anything better to do?
Leonard: Better than watching a guy in a fur cloak ride a girl's bike? Nope.
Stuart: That's it, you just lost bathroom privileges at the comic book store.

Bernadette: Why are you dressed like that?
Stuart: Oh, uh, Howard thought it'd be funny to tell me it was a costume party.
Bernadette: That wasn't nice.
Stuart: No, but he almost died, so we're cool.

Bernadette: You all right?
Howard: I'm fine. Just a little embarrassed I had to be carried down the stairs like a baby. (To Penny) Thanks.

Penny: What about your weird relationship with him?
Leonard: That's different. I'm like the little girl in Poltergeist and he's the creepy thing in the TV.

Raj: You know, if you think about it, tonight was kind of like a real-life Game of Thrones.
Amy: How?
Raj: Well, Howard eating that pistachio was like when King Joffrey got poisoned.
Penny: Okay, well, that was murder, this was an accident.
Raj: Okay. But you using Sheldon to do your dirty work is like when Cersei used the Kings Guard to do her bidding.
Sheldon: Cersei uses her body to manipulate men. Penny just takes me to The LEGO Store.
Raj: Okay. Oh, how about this? Stuart's dressed like a brother of the Night's Watch, and they don't have sex.
Penny: There you go.
Leonard: That's true.
Sheldon: Fair enough.

Leonard: It just said Italian sub. I had no idea mortadella has pistachios in it.
Sheldon: Interesting fact, in Italian, the morta in mortadella means death.
Amy: Sheldon.
Sheldon: I didn't say fun fact. I'm not a monster.
Bernadette: He's gonna be okay.
Sheldon: Now it's a fun fact.
