Howard: I love you. And I'm not just saying that because your breasts are gonna get bigger.

Sheldon: You're kidding! What kind of maniacs have coitus in someone else's bedroom?!
Howard: Thank you, Pasadena! Good night!

Howard: I'd like to dedicate my last song of the evening to my wife, best friend, and now the mother of our child. I love you, Bernie.
"Havin' my baby / What a lovely way of sayin' / How much you love me / Havin' my baby / What a lovely way of sayin' / What you're thinkin' of me"

Penny: That was such a fun night.
Leonard: Probably 'cause you got to see your man up there rockin' the mic.
Penny: Yeah, yeah. I was a little surprised when you decided to beat-box.
Leonard: Oh, that was really an asthma attack. I just sold it.

Bernadette: You guys can go in if you want.
Penny: No, we're a team. If you can't go in, we're not going in.
Amy: Then why are we drinking?
Penny: Okay, it's not like she's got the Christ child in there, all right?

Penny: So, you gonna get up there later?
Sheldon: A microphone, a room full of inaccurate depictions of Polynesian religion, and a captive audience to hear about it? You bet I am.

Amy: How are you doing?
Sheldon: Oh, wonderful. I'm being musically encouraged to bust a move. If I knew what that meant, I might just do it.

Penny: Oh, it's Leonard. He says Sheldon's drunk and they're gonna do karaoke if we want to join them.
Penny: That sounds fun.
Amy: Oh, no. Sheldon's drunk texting me.
Bernadette: What's it say?
Amy: "Would you like to sing karaoke with us."
Bernadette: How is that a drunk text?
Amy: He used a period instead of a question mark. He's so wasted.

Leonard: Can you focus on what we're talking about?
Sheldon: All right. Look, now, this may be the rum talking, but as long as the unpinning rate of the vortices is kept within 1.1 and 1.3, the Magnus force issue should be negligible.
Raj: Even drunk, he's still smarter than all of us.
Sheldon: And stronger. Yeah, who wants to see me beat up the bartender?
Leonard: I'd enjoy that.
Sheldon: Nah, she's a good kid.

Raj: Look at that. You've known you're gonna be a father for less than a day and you're already stepping up.
Leonard: I'm telling you, you got this.
Howard: Maybe you're right.
Sheldon: Of course he's right. You and I both know how hard it is growing up without a father. That's why I'm confident you're gonna be the best dad you can be.
Howard: Thank you, Sheldon.
Sheldon: You're welcome. And if he has twins, we can do all kinds of neat experiments on them.

Bernadette: We were out one night, and things got a little spontaneous.
Amy: Oh, that sounds juicy.
Bernadette: Well, Sheldon was going on and on about time zones and railroad schedules, and I went out-
Penny: Wait, I remember that. Hang on. You did it at our place?
Bernadette: Kind of on Sheldon's bed.
Amy: What?!
Penny: No!
Bernadette: I was headed to the bathroom, and I passed Howie on his way out. Usually he says, "Do not go in there," but this time he said, "Hey, let's go in here."

Leonard: I'm not seeing anyone using liquid helium vortices like this.
Howard: I'm not finding anything either.
Raj: That's a good sign.
Sheldon: Oh, wait, I found something.
Howard: Damn. What is it?
Sheldon: This video. The baby panda sneezes, and the mama panda gets so scared.

Amy: How could you do that?
Bernadette: I'm sorry, but you know what it's like when you're with your man and one thing leads to another.
Amy: I do know what that's like. I really do.

Howard: Maybe that's an idea, guidance systems for drunk people.
Raj: They have that. It's called Uber.

Sheldon: You guys, the bathroom here is amazing. There's people cooking in it.
