Amy: What are you reading?
Sheldon: This article says the peak age for making a Nobel Prize-winning discovery is 40.
Amy: So?
Sheldon: So, I'm running out of time.
Amy: That's ridiculous, you're a brilliant man. The best years of your life are still ahead of you.
Sheldon: Oh, you have to say that, you're sweet on me.

Zack: Penny, what's up?
Penny: Hey, uh, so I've been thinking about it and I want to take the job.
Zack: Oh, bad news. When my fiance found out that I was offering a job to my ex-girlfriend, she said it was a stupid idea and threw a shoe at me.
Penny: Oh, so there's no job?
Zack: Nope, just a little bump on my forehead.

Amy: What happened to learning the unicycle?
Sheldon: Oh, I stopped that, it was dumb. Uni, bi, tri, menstrual, all cycles are dumb.
Amy: You said juggling was dumb, too.
Sheldon: Well, it is. If I wanted to hold three things at once, I'd wear cargo pants.

Amy: His mother warned me. Everybody warned me. Actually, he warned me.

Howard: You know what? I'm with Leonard, this isn't cool.
Leonard: Thank you.
Raj: I disagree. Penny is a strong, independent woman. The more you try to control her, the more she'll push back.
Leonard: So you think it's okay?
Raj: Oh, no, she's gonna leave you for someone, might as well get it over with.

Amy: What are you doing?
Sheldon: I'm returning this stuff to Howard.
Amy: Oh, Bernadette made me promise if you didn't want it, we'd give it to a homeless clown.

Amy: Sheldon, is it possible that when things get really difficult, you just give up?
Sheldon: Are you calling me a quitter?
Amy: Well, if you honestly-
Sheldon: This conversation is over.

Leonard: So you think it's fine if she works for Zack?
Howard: I don't know. Maybe.
Raj: Well, he is much more attractive than Leonard.
Howard: Yes, but that's gonna be true of a lot of guys she works for.
Leonard: Yeah, but she also used to sleep with Zack.
Howard: Again...

Howard: So you told her she was being dumb?
Leonard: No, I told her she was being not smart. Which was dumb.
Raj: Why did you even go to dinner with the guy?
Leonard: We covered this, I'm dumb.

Bernadette: I would never let Howard work with an ex.
Penny: What, you wouldn't trust him?
Bernadette: I wouldn't trust her. He's thin and sexy like a Jewish greyhound.
Penny: Yeah, that - that is the sexiest dog.

Bernadette: And I'd like to think Howie wouldn't take a job I was uncomfortable with.
Penny: 'Cause he's scared of you?
Bernadette: Terrified.
Penny: Yeah.

Penny: So he's my ex-boyfriend, who cares? I can't believe Leonard would be so insecure.
Bernadette: Really? I have no trouble believing that at all.
Penny: And Zack's engaged. Leonard has no reason to feel threatened.
Bernadette: We're talking about the same Leonard, right?

Amy: Where did you get it?
Sheldon: Howard said I could borrow it, Bernadette said forever.

Leonard: You're not really considering working for him, are you?
Penny: Well, maybe, I mean, it seems kind of perfect. I have sales experience, and I've been a waitress, so I have restaurant experience, and if he's figuring out my Christmas bonus, we could buy a boat.

Amy: Have you tried letting go of the rope?
Sheldon: What, are you crazy? I'm on a unicycle.
Amy: All right, well, have fun.
Sheldon: Wait, I need help getting down.
Amy: Well, what do you want me to do?
Sheldon: Drag out our mattress and put it over here, then go across the hall, get their mattress and put it over here. But before you do any of that, scratch my nose.
