Amy: Sheldon, I'm freaking out.
Sheldon: Well, is this still about the Nobel Prize?
Amy: Yes, it's about the Nobel Prize!
Sheldon: And back to the mean voice.

Howard: Hey. You still mad?
Bernadette: Are you still a jackass?

Bernadette: Hey, what you got there?
Howard: Oh. [stammers] Just tossing out this old helmet I don't need. I thought you were at the park.
Bernadette: We were. The kids got sleepy.
Howard: Great story. I need to make a phone call.
Bernadette: Howard, why do you look all guilty? Like when I catch you deleting your browser history?

Sheldon: Bebe.
Bebe: What's wrong?
Sheldon: Nothing. I just wanted to make sure it worked. Also, I changed my mind. It's fun to say your name. Bebe. Bebe. [Bebe closes the tank] Bebe. Bebe. Bebe. Bebe.

Amy: Shall we?
Sheldon: One second. Is the pH between 7.2 and 7.8?
Bebe: Yes.
Sheldon: Is the water drained and replaced after each use?
Bebe: Yes.
Sheldon: Is the saline level 30%?
Bebe: Yes.
Sheldon: Does your filtration system use ultraviolet light to kill bacteria?
Bebe: Yes.
Sheldon: I don't need to get in. I'm relaxed already.

Bebe: All right, are you ready?
Leonard: I'm not saying this is why we came, but can I close the lid on him?
Bebe: No. [Leonard tries to hand her money] No.

Bebe: Okay, just a heads up. People have different experiences in the tanks. Uh, some people experience perfect calm. Some people sleep. Some people even reported having visions. But if at any time you feel uncomfortable, just press the panic button and say, "Bebe."
Sheldon: [laughs] That's a stupid word.
Bebe: That's my name.
Penny: What do we push if we feel uncomfortable?

Amy: [inner monologue] Wow, this is really dark. There's no difference between my eyes being open or closed. Open, closed. Open, clo- Nope, same thing.

Sheldon: [inner monologue] Hmm, this is nice. It's sort of like floating in space. But better because my eyeballs haven't frozen.

Howard: Are your eyes closed?
Raj: Yes. What is it? Show me.
Howard: Okay, open them.
Raj: You bought me a scooter?! No, I bought me a scooter!
Raj: Then why did you make me close my eyes?
Howard: I wanted to see the expression on your face when you saw how happy I was.

Howard: [engine starts] Check it out. [engine revving] That there, son, is 12 horses of "eye-talian" thunder.

Raj: Wait, one second. Won't Bernadette be mad when she finds out?
Howard: She's not gonna. I'm keeping it here at the university.
Raj: Ah. My dad kept a secret at work, too, but it was his receptionist.

Amy: Plus, Sheldon's freaking out 'cause we got in trouble.
Leonard: Well, I've got him distracted for a while.
Penny: Doesn't he know how to solve those?
Leonard: Normally, yes, but I switched the stickers around, so I don't even think it's possible to solve-
Sheldon: Solved it.
Leonard: What? No, you didn't.
Sheldon: Not the cube, but the puzzle of why I couldn't solve the cube. Solution: you switched stickers 2, 9, 32, and 51.
Penny: Really? This thing has numbers?
Sheldon: Anything has a number if you assign it a number, friend number four.
Leonard: Top five, not bad.

Amy: So apparently, if we win, I'll be the fourth woman ever to win a Nobel in physics.
Penny: Wow, that's a big deal.
Amy: Yeah, tell me about it. This morning, I blew through my antiperspirant in, like, an hour.

Penny: Sweetie, you just need to relax. You know what I like to do?
Sheldon: Numb your brain with alcohol and watch a reality show where wealthy people pick fake arguments with each other?
Penny: Hey, don't knock it until you've wasted a couple hundred hours of your life.
