Bernadette: So where's he taking you?
Amy: Oh, he's coming here. I'm actually making dinner.
Bernadette: Oh, that's a big step.
Amy: It is?
Bernadette: Yeah, you're inviting him into your home. It's intimate. It's where your underpants live.

Amy: Do you realize it took me five years to get a massage from him?
Beverly: Oh, well, that still could be a big step for Sheldon.
Amy: Three minutes. And he used a kitchen timer. I felt like a soft-boiled egg.

Sheldon: That's not her. That's not her. That's not her. That's not her.
That's not her. That's not her. That's not her. That's not her.
Leonard: Really? The old Asian man is not your Meemaw?
Sheldon: And that's not helpful.

Sheldon: If any of you are looking for something to do on Valentine's Day, Amy and I'll be streaming our first-ever live episode of Fun With Flags. You're welcome to join us as we celebrate the timeless love affair between wind and flapping fabric.
Leonard: Penny and I have dinner reservations that night, but any other time, no.

Bernadette: Who's Trent?
Howard: Oh, he's our fan.
Bernadette: Fan of what?
Howard: Uh, did you forget? We're in a band.
Bernadette: You mean because you played one time in the comic book store?
Howard: And at the children's hospital until they asked us to leave.

Sheldon: Okay, here it comes. You tried to take care of me when I was sick, and I was mean to you. There's no excuse for that. And I'm truly sorry.
Leonard: Thank you. I appreciate that.
Sheldon: I want you to know that that is sincere. I do feel bad. I'm not just saying it to be included on your trip.
Leonard: Appreciate that, too.
Sheldon: Terrific. Now all that's left is for you to invite me to come. Me to ask, "Are you sure?" You to say, "Absolutely." And then me to bring it home with, "How could I say no to that face?"
Leonard: You're still not coming.
Sheldon: What? But I apologized and I meant it. I know that we don't play this game very often, but you're doing it wrong.
Leonard: Sheldon, I accept your apology, but you upset a lot of people while you were sick. I'm not in a position to just say you can come.
Sheldon: Well, all right. What if I apologize to all of them?
Leonard: Fine, if you apologize to everyone, they all say it's okay, then yes, you can come.
Sheldon: Challenge accepted! Sounds like it's time for the Sheldon Cooper Apology Tour.
Leonard: Well, I hope it's as much fun as the Sheldon Cooper Spell-Checks Local Menus Tour.
Sheldon: My goodness! Do you remember "comes with apsparagus"?

Howard: Look at this. Trent is rebuilding a vintage motorcycle.
Raj: That is so cool! Old broken things are so much better than new things that work.

Penny: You know, she's my mother-in-law. Why can't I bond with her like that?
Bernadette: Amy's with Sheldon, who she loves like a son. You're with her son, who she doesn't.

Amy: Sheldon, I understand that you're upset because you feel left out, but I don't know why we're even talking about this. Just apologize to them.
Sheldon: Fine, if that's what it takes to go on their dumb trip.
Amy: Maybe you could try apologizing because you actually feel bad. It's called empathy. It's something you could work on.
Sheldon: I have empathy. Watch. Leonard made me soup, and I was mean to him.
Amy: Great. Now try it as if this isn't your first day as a person.
Sheldon: Fine. Leonard made me soup, and I was mean to him. Hey, I felt a little something. Let me try again. Leonard made me soup, and I was mean to him. I was mean to him. He must have felt terrible. Oh, now I feel terrible.
Amy: Neat! Glad I could help.

Sheldon: People are also delighted by your love of pranks. (Softly) For example, Leonard has no idea what I did to his coffee. It wasn't "replace it with Folger's crystals," I'll tell you that much.

Beverly: I'm not surprised Leonard chose to avoid picking me up. He's battled intimacy issues his whole life. Does he have difficulty maintaining erections?

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

Howard: If you really care that much, there are apps now that'll let you hire people to do stuff like errands and wait in lines.
Stuart: People are actually waiting in lines as a job? Boy, makes me feel better about my life.
Howard: Some of these guys make over $20 an hour.
Stuart: And now I feel worse again.

Penny: All right, my advice to you is do it at her place so you can leave when you need to. Uh, tell the truth, make it quick and be prepared for tears.
Raj: Oh, I'm gonna do a pre-cry before I go in there. Really dry myself out.
Leonard: She meant Emily.
Penny: No, I - I really didn't.

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.
