Leonard: Well, I-I have to go to the clinic for Zack and Marissa on Monday, and I'm supposed to save myself until then.
Amy: Sounds like maybe Penny's not totally on board with that plan.
Leonard: Well, she said she was. But she also said I looked dope. Honestly, I don't even think I looked fly.

Leonard: Okay, look, they can't have kids of their own, and they like that I'm smart, and they want that for their child.
Wyatt: No, I get it.
Penny: You do?
Wyatt: Sure. Back on the farm, we had a prize stallion. We didn't let that just go to waste; we put him out to stud.
Penny: No, no, this is this is a little different than that-
Leonard: No, no, hey, hey, hey, hey, hey, hey. Uh, you were comparing me to a prize stud. Go on.

Wyatt: So let me get this straight, Leonard. She doesn't want to have your baby, but her dumbbell ex-boyfriend does.
Leonard: Well, I- No, I wouldn't say it like that.
Wyatt: How would you say it?
Leonard: Uh, same words, just less angry.

Leonard: Hey, Wyatt.
Wyatt: Leonard. Hey, that's a hell of a handshake.
Leonard: Ah, well, you know, I've been taking vitamins.

Penny: Dad, uh, come on in, sit down. Can I get you something to drink? Maybe a beer?
Wyatt: Sure, if you're having one.
Penny: Okay.
Wyatt: And why wouldn't you, since you're not pregnant?
Penny: Um. Leonard wants to have a baby with my ex-boyfriend Zack.
Leonard: How 'bout those Cornhuskers?

Penny: What are those?
Leonard: Oh, vitamins. Zack wants me to take them to increase my virility.
Penny: Zack used the word "virility"?
Leonard: He may have said "wiener power."

Zack: Well, Leonard, we were hoping you'd go in on Monday.
Leonard: Okay.
Marissa: And they say, for the best results, between now and then, you shouldn't have sex.
Zack: Sorry, bro, I know it seems impossible to go for five days without, but I believe in you.
Leonard: Five days? My record is 24 years.
Penny: Uh, I think that also means no flying solo.
Leonard: Oh. Then my record is 14 years.

Penny: Are you okay?
Leonard: (pants) That depends. What-what color are my eyes?
Penny: I don't know, brown? No, green. No, wait, brown.
Leonard: Oh, good, I'm awake.

Penny: You're having a bad dream.
Leonard: Oh, thank God. I was eating my friends. Well, one friend and one acquaintance.
You know what, Bert's okay. Two friends.

Penny: Plus, I'd be working for Bernadette. I don't know if that's a good idea.
Leonard: Look, I-I know she can be difficult, but she's no match for you. Whatever she dishes out, you can give it right back double.
Penny: What the hell is that supposed to mean?
Leonard: There you go.

Penny: You know, it was nice of Bernadette to offer, but I'm not sure it's the right move for me.
Leonard: Well, what are you talking about? If you were in charge of her project, wouldn't that be a promotion?
Penny: Well, yeah, but it's not the most important thing. Aren't you always saying it's about the work, not more money or a better title?
Leonard: All the smart things I say, and you remember the dumb one.

Penny: They couldn't have picked a better person. [Leonard chuckles and picks up his phone] Are you calling Zack?
Leonard: No, Sheldon. Would you say that last part one more time?

Penny: And we ran into Zack.
Leonard: Oh. Yeah? How's he doing?
Penny: He got married.
Leonard: Oh. Well, that's nice.
Penny: Yeah, and he sold his company for a fortune and retired.
Leonard: Huh. And you ended up with me, so everybody wins.
Penny: Wait. You're not jealous of Zack, are you?
Leonard: What? Oh, absolutely not. In fact, he should be jealous of me because I have you. And a dungeon with over 30 rooms left unexplored because no one thought to search for secret doors under the wizard's throne.
Penny: Oh. You know, I'd like to go exploring.
Leonard: Really?
Penny: Mm-hmm.
Leonard: Well, I'll get the dice back out.

Leonard: How was ladies' night?
Penny: It was fun. Amy got drunk and kept telling us that Sheldon's chest is smooth like a porpoise.
Leonard: Well, it does squeak when you touch it.

Leonard: What is up with you two?
Stuart: Well, it's kind of hard to explain. Uh, you know when things are going great, but you worry that any minute you might screw everything up?
Penny: No.
Leonard: Yes. If you really like her, you can't let fear get in the way. You have to move forward.
Stuart: And at a certain point, the fear of losing her goes away?
Leonard: I will let you know.
