Penny: I'm so sorry to hear about you and Howard.
Bernadette: Thanks. I just didn't think he was the kind of guy who would be doing weird stuff online.
Penny: Really? Wow, I thought it was so obvious, but okay.

Penny: Look, I know it's hard, but I think the best thing to do after a breakup is to take some time and be by yourself.
Bernadette: Yeah, that's healthy.
Zack: Hey, babe, ready to go?
Penny: Do as I say, not as I do.

Sheldon: *knock knock knock* Penny! *knock knock knock* Penny! *knock knock knock* Penny!
Penny: Sheldon, go away. I'm making a video.
Sheldon: Oh, I'm sorry. I'll come back when you're alone.

Penny: I went out with him because he's great. And if I kept going out with him, I probably would've married him, and that's a little scary because I just don't think I'm ready for that. You know, plus I have got to learn how to spell Hofstadter. I-I know there's a "D" in there, but it keeps moving every time I try and write it.

Raj: What, y-you stole our Bitcoin?
Sheldon: Oh, calm down. All I did was sneak onto your computer and download your Bitcoin onto a flash drive.
Leonard: What?
Sheldon: I'm not keeping it. I just wanted to watch you sweat.
Howard: If you want to watch him sweat, walk up a flight of stairs with him.
Sheldon: I've waited seven long years, but it finally happened.
Leonard: Where's our money?
Sheldon: That's the best part. It's on the Batman flash drive on your key chain. You've had it in your pocket all along.
Leonard: Sheldon I lost that key chain years ago.
Sheldon: Really? D-D-Did you look under things?

Stuart: Huh. What's that? Ooh, Batman flash drive. Pretty cool. Huh, if I erase this, I could probably resell it for, like, ten bucks. Things are finally going my way.

Howard: Do you think Zack stole it?
Penny: No, he doesn't know how to steal Bitcoin. I mean, he waves at trucks.

Sheldon: Oh please, I have grudges that go back to preschool. Someday, I'm gonna find a grown-up Elaine Dwyer and eat her favorite crayon while she watches.
Amy: Is that why there's an Elaine Dwyer on our guest list?
Sheldon: Yes. That night, I'm going to have the first dance and the last laugh.

Sheldon: Speaking of something I find interesting, did anyone read that article about Bitcoin I sent you?
Howard: Yeah, I can't believe a single Bitcoin is worth about $5,000 now.
Leonard: Wait, didn't we mine some a few years ago?
Sheldon: It was seven years ago.
Howard: Oh, yeah, I remember that.
Raj: Really? All I can remember from seven years ago is I couldn't get Kesha's "Tik Tok" out of my head.
"Tik Tok, on the clock" Whoa, welcome home, Kesha.

Leonard: If it's not tangible, how do you know it's not just gonna vanish tomorrow?
Howard: Really? You're dating Penny, and you're gonna poke at something that could vanish tomorrow?

Raj: Hey, Stuart. You want to mine some Bitcoin with us? We'll write the program, you bring the snacks?
Stuart: Too rich for my blood.

Leonard: Oh, yeah. We did it without you.
Sheldon: And do you remember what happened next?
Howard: Your mom called my mom and said we were being mean?
Sheldon: And after that?
Howard: You said that someday we'd regret this.
Sheldon: And do you know what today is?
Leonard: The day we found out we're rich and none of it is yours? (Leonard, Howard and Raj high-five)

Raj: Mining for coins sounds so manly. Ooh, we should sing a mining song.
Leonard: Do you know a mining song?
Raj: I don't know. Does "Tik Tok" by Kesha count? Because it has tunneled its way into my heart.

Penny: Well, weddings aren't about the location. They're about standing up in front of your family and friends and promising that Sheldon will never move back in here.

Penny: Hey. What are you guys doing?
Raj: Uh, we have a bunch of Bitcoin on an old laptop, and it could be worth, like, a lot of money.
Penny: What-- You're kidding.
Leonard: No. We-we could be sitting on a fortune.
Penny: Okay, let the record show, I did not marry you for money, but you just got way more attractive.
