Leonard: All right, pressure's off.
Howard: Wanna see a movie?
Sheldon: Popcorn's on me.

Leonard: So, what are you guys gonna do today?
Amy: Well, Sheldon was supposed to go to this party with me this afternoon, but I don't think that's happening.
Sheldon: Oh, that was never happening.

The Flash: Here, it's on the house.
Sheldon: The first one's free? Flash, how do you stay in business?
The Flash: You want to know my secret? I bought stock in Marvel.

Sheldon: Are you okay? Oh, I'm fantastic, never been better. I had my first energy drink and I feel great. Hey, you guys want to wrestle? We can do arm, thumb, mud, sumo. Nah, we're not fat enough, or wearing diapers.

Sheldon: I am cool. This is YooHoo. Chocolate milk's delicious, watery cousin.

Raj: Well, I think the first thing we should get rid of is that tone.

Howard: If you're tired, have some coffee.
Sheldon: What? You have some coffee.
Howard: I am having coffee.
Sheldon: And look how irritable it's making you!

Sheldon: I don't think I can go much longer.
Leonard: It's been three and a half minutes, wake up!

Penny: Oh, I'll go. I like a party.
Amy: Well, to be honest, it's not like a "party" party. It's more like a gathering where scientists of different disciplines get together to share their work and keep current on what's going on in other fields. I don't know why I called it a party, sorry.

Bernadette: I should probably keep this in case we have a girl.
Raj: Oh, that's a nice one. Was it yours when you were little?
Bernadette: My dad built it for me.
Raj: Wow, it's so cute.
Bernadette: This was the husband and this was the wife. They'd go out on adventures together. Cruises, skiing, horseback riding. That was really me just duct taping them to our dog.
Raj: Oh, and did they have kids?
Bernadette: They did, but the mommy and daddy didn't like them, so they shipped them off to an orphanage I made out of a shoebox.
Raj: Yeah, that's not worrisome at all.

Bert: Well, I guess this is kind of a bust. You don't have to stay. I'm gonna start cleaning up.
Penny: Okay.
Amy: I feel so bad about leaving him here.
Penny: Oh, it's funny, I was just thinking the same thing about you.

Bert: Hey, listen, could you not say anything about this to the people at the university? You know, 'cause you're you and I'm me, and it's kind of embarrassing.
Penny: Wait, what do you mean "she's her"?
Bert: Well, you know how Amy's the coolest girl on campus, right?
Penny: No.
Amy: No.
Bert: Oh yeah, everybody thinks so.
Penny: What? You tell me about your foot fungus, but this is a secret?

Bert: And when Amy started using a solution of chromic acid and white vinegar to clean all her lab equipment, all of a sudden, everybody was doing it.
Penny: You trend setter!
Amy: Just the right idea at the right time.

Leonard: I'm gonna get some coffee. You want some?
Sheldon: Uh, you're really going to have caffeine in front of me when I'm trying to get my life back on track?
Leonard: Uh, okay, let's pretend you do have a problem.
Sheldon: I do.
Leonard: You don't.
Sheldon: Yeah, but I do.
Leonard: No, you don't! But let's say you do. And don't say you do, because you don't! Now, wouldn't you think that throwing yourself into your work would be the best way to deal with it?
Sheldon: With what?
Leonard: Your problem.
Sheldon: I thought I didn't have a problem.
Howard: That was painful to watch.

Raj: So where are we going?
Bernadette: I don't know.
Raj: Okay. How Thelma and Louise of us.
