I took a temp job as a waitress forever ago and I can't quit, because guess what? I can't do anything else.

Leonard: Listen. I could never do what you're doing. I'd be terrified.
Penny: Well it's scary for me too.
Sheldon: I'm fine with it.
Leonard: My point is: just because I couldn't do it doesn't mean you shouldn't. And I'm proud of you.
Penny: Okay. Thank you.

Penny: Are you going to lay on the floor and pretend to be dead all night?
Stuart: What do you think I'd do at home?

Sheldon: No, I've changed. Like the frog who's put in a pot of water that's heated so gradually he doesn't realize he's boiling to death.
Penny: Or you're the frog who's been kissed by a princess and turned into a prince.
Leonard: Or, you're just a tall, annoying frog.

Penny: Who's the murderer?
Raj: Any question but that.
Penny: Sorry ... hey, who's not the murderer?

Sheldon: I have spent years turning this lump of clay into an acceptable conduit for my will, and then you came along and reshaped him, with your newfangled ideas and your fancy genitals.
Penny: Are you gonna let him talk to me like this?
Leonard: "Fancy" sounds like a compliment.

Penny: I can't believe Leonard is spending hundred of dollars on scalped tickets.
Amy: Last week, you spent that on a little dress.
Penny: Yeah, but those tickets only get him into Comic-Con. That dress gets me into anywhere I want.

Penny: Okay, sex is not what makes you a grown-up.
Bernadette: Yeah, or you'd be the oldest one here.
Penny: Really? Is that how you talk to your mother?

Leonard: Plus, I'm not sure it's a great idea to take Penny to where wine comes from. [chuckles] What? It's a joke. Oh, come on. We bust on each other. I wear dorky glasses, you might have a problem -- it's all for laughs.
Penny: That would really piss me off if I didn't have a buzz going on.

Leonard: In fact, if you want, we can do it right here on Sheldon's spot.
Penny: That is the least sexy thing anyone's ever said to me.

Penny: Hi. Want to do yoga with me?
Leonard: Um, let me just have some coffee first, and then I'll have the strength to tell you how much I won't be doing that.

Bernadette: Why don't I get you a job at the Sitting Around All Day Wearing Yoga Pants Factory?
Penny: They're comfortable.

Oh, Bernadette, please play my clarinet.

Raj's poem

Sheldon: I'll have a diet Coke.
Penny: Can you please order a cocktail? I need to practice mixing drinks.
Sheldon: Fine... I'll have a virgin Cuba Libre.
Penny: That's... rum and Coke without the rum.
Sheldon: Yes, and would you make it diet?
