Sheldon: Oh, I watched a video of the hagfish producing mucus, so I'm gonna change my answer and eat SpongeBob.

Leonard: Do you remember when you accused me of trying to sabotage our wedding?
Penny: Uh-huh.
Leonard: I've been thinking about it and you might be right. But the good news is I'm pretty sure I know why.
Penny: I'm listening.
Leonard: Penny, after all these years I still feel like maybe I don't deserve you.
Penny: Okay, that is the lamest excuse you could have possibly come up. But I get it.

Sheldon: Okay, your turn.
Amy: Hmm. Seal, hagfish, SpongeBob SquarePants.
Sheldon: Well, I'd befriend SpongeBob but he's not real, so I can't do that, can I?
Amy: But you can pal around with a hagfish?
Sheldon: Hey, let's not pull at that thread.
Okay, I'll fight SpongeBob, because he's so friendly we'll just end up tickling each other. Um, I'll befriend the seal, because he's trainable, which was the problem I'm having with my current friends. Which means I'll have to eat the hagfish.
Amy: Isn't that gross? I mean, a hagfish can produce enough mucus to fill a bucket in a minute.
Sheldon: I know. It makes its own gravy, it'll slide right down.

Sheldon: You know, for a Thanksgiving buffet in an aquarium cafeteria, that was really bad.
Amy: You're just upset 'cause they ran out of Pilgrim hats.
Sheldon: They gave one to that baby. He wasn't even awake.
Amy: Well, it wouldn't be a holiday without you being mad at a baby.

Howard: I'm gonna check the temp on the tub.
Bernadette: Don't make it too hot.
Howard: Sorry, but "too hot" is the only temperature I come in.
Bernadette: Look at that. You shaved it all.
Howard: You're welcome.

Penny: Hey, guys.
Leonard: Hey. What are you doing here?
Bernadette: We heard there were some sexy scientists working hard all weekend.
Penny: Yup, so we brought you some lunch and we are gonna go look for 'em.

Raj: Hello?
Claire: Hey, Raj. It's Claire. How are you?
Raj: Hi. I'm good. Really good.
Well, I don't know why I said "really good." I'm just regular good. I really just wanted to sound confident. And that "really" was a real "really", not a fake "really" like the first "really."
Claire: Really?
Raj: I don't know. I lost track and I missed my exit.

Leonard: They've been out there a while.
Amy: I hope everything's okay.
Sheldon: I wonder what they're talking about.
Penny: (eavesdropping at the door) If you guys would shut up, I could tell you.

Raj: Dude, if we do this, we're gonna need a cool band name.
Howard: You know, I've actually had one I've been sitting on for years.
Raj: Really?
Howard: It was for this power trio I tried to put together in junior high, but I was short two friends.
Raj: What is it?
Howard: Footprints on the Moon.
Raj: I just got chills.
Howard: So did I.
Stuart: Me, too. But I might have Lyme Disease.

Leonard: Oh, hey. I just heard back from the liquid helium guy.
Sheldon: What'd he say?
Leonard: He's got what we need and can meet us tonight.
Sheldon: Oh, really? You know I don't like buying things at night.
January 7, 2009. I went to the Ralph's at 11:30pm to pick up Cracklin' Oat Bran for the morning, and what did I see?
Leonard: The man restocking the cereal shelves.
Sheldon: That's right. And what did he do?
Leonard: He handed you the box directly and called you Stretch.
Sheldon: (shudders) It's like it was yesterday.

Penny: Well, so how does it work?
Stuart: Ah, well, it shows me all the single women in a five-mile radius who are using the app. If I like the way they look, I hit thumbs up. If I don't, thumbs down.
Bernadette: Oh, what would make you give a girl a thumbs down?
Stuart: First time it happens I will let you know.

Amy: Sheldon, why don't you get a new computer? You know that one's out-of-date.
Sheldon: Oh, but I like this computer.
Amy: The video is failing, and the sound is cutting out.
Sheldon: I'm sorry, I didn't get that.
Amy: The video is failing, and the sound is cutting out.
Sheldon: I'm sorry, one more time. The sound is cutting out. (Amy holds up a sign) I can't read that. The video is failing.
Amy: Get a new computer.
Sheldon: What?
Amy: Get a new computer.
Sheldon: What? (Answering phone) Hello?
Amy: Get a new computer!

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.

Bernadette: Hey, you know who went out on a date the other night? Stuart.
Penny: Oh, good for him.
Bernadette: I thought so, too.
Penny: So is she, like, homeless, or framing him for a crime?

Raj: Oh. You know what? I'm gonna let them know that I'm here with you and that they're busted.
Penny: No. You know what? Don't, don't. Let's let them think they're getting away with it.
Bernadette: Yeah, let's see how deep a hole they can dig for themselves.
Penny: Mmm-hmm.
Raj: Interesting. I mean, it's not testicles on a cryostat, but I like it.
