Leonard: Soup, sandwiches and emasculation, just like my mom used to make.

Howard: I don't know if we have enough solder to finish these circuit boards.
Leonard: We had a full spool yesterday.
Howard: What can I say, I play hard, I solder even harder.

Amy: Sheldon, just tell me.
Sheldon: It might be easier to show you.
Amy: Okay.
Sheldon: We'd have to take your car.
Amy: All right.
Sheldon: And I'm gonna need you to sign a non-disclosure agreement.
Amy: Well, I signed one before we slept together. Why not now?

Leonard: What are we gonna tell the girls?
Howard: It's not a problem.
Leonard: I mean without lying.
Howard: And now you've made it a problem.

Cinema Worker: Hey, guys, thank you for being a part of our test screening. You're about to be one of the first audiences to see Suicide Squad.
Leonard: Hey, you were right.
Howard: Well, I keep telling you, good things happen to bad people.

Bernadette: Sometimes he solders at home with his shirt off. It's like a beer commercial.

Cinema Worker: Uh, were gonna get started in a couple minutes. Enjoy.
Leonard: Who are you texting?
Howard: Raj. He really wants to see this movie.
Leonard: He'll never make it in time.
Howard: I know. I want to make him feel bad.
Leonard: "Ha, ha. Leonard and I are about to see Suicide Squad. Spoiler alert, when I see you I'm gonna spoil it." You're a good friend.

Leonard: After you wrap the body in reflective tape, the ends get Teflon tape so we can get a tight seal.
Penny: Like this?
Leonard: Yeah, perfect.
Penny: Oh.
Leonard: And it helps to have small, delicate fingers. So don't be discouraged if you can't do it as fast as me and Howard.

Leonard: This is cool. When was the last time you and I built something together?
Howard: Scientifically? A little over a year ago. LEGOs? Last week in my room.
Leonard: If there was a Nobel Prize for Millennium Falcons that fall apart when you pick them up, we'd be set.

Leonard: Penny says they're having fun working on the prototype.
Howard: Remember when her fun was nightclubs and drinking games?
Leonard: I know. I'm lowering the bar so slowly. This time next year she'll have a coin collection.

Amy: So, no one else knows about this?
Sheldon: Only you.
Amy: Thank you for trusting me.
Sheldon: What good is having a girlfriend if you can't unload your psychological sewage on her?
Amy: That's me, your emotional outhouse.

Cinema Worker: Excuse me. You guys interested in a free screening of an upcoming movie?
Leonard: Oh. Sorry, we can't.
Howard: Well, hang on. What movie is it?
Cinema Worker: Oh, I can't tell you. But it does star Will Smith.
Howard: Wait. I bet it's Suicide Squad. Let's check it out.
Leonard: What about the girls?
Howard: Penny just said they're having fun. Honestly, you want to wrap tape around a bunch of pipe fittings all afternoon?
Leonard: Okay, we'll take 'em. But, I swear, if it's Will Smith in Shark Tale 2, it better be at least as good as the original.

Howard: Ready for dinner?
Penny: Yeah.
Bernadette: Should we invite Raj?
Raj: (Inside the closet) Yes.

Amy: Okay, why do you have a bin of pine cones?
Sheldon: I used to collect them as a child. The spiral of scales open in the Fibonacci sequence. A fact that, when you tell your brother, gets a golf ball thrown at your head.

Bernadette: Okay. Okay, how about this? They don't know you're here with us, so you hide in the closet. When they show up, we'll hear whatever their dumb story is about where they were, we'll pretend to believe them and just when they think they got away with it, you jump out.
Penny: Yeah, that's pretty good.
Raj: I love it, I'll be all like, "Busted!", and they'll be like, "What?", and then we'll all be like, "Oh, yeah!" Yeah, I get it. I wouldn't make out with me, either.
