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.
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.
Leonard: Waah. I don't want a table!
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.
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.
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?
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.
Leonard: Look, if you want to break up, just say it.
Leonard: No, no, no, I take it back, don't say it. Just hate me but stay with me. It worked for my parents.
Penny: Listen. I don't want to break up with you.
Penny: Why are you sitting in the stairwell?
Sheldon: Leonard told me to stay.
Penny: Oh. Well, good boy.
Penny: You want to come with me?
Penny: Come on boy! Come on! Let's go!
Sheldon: I've read that there are great yogis who have such mastery over their bodies they can draw water in through their genitals.
Penny: Yeah well I don't think we're going to get to do that today.
Sheldon: Too bad. Seems like a good way to drink a milkshake without getting brain freeze
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.
