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.
Penny: Let's get married?
Penny: Leonard Hofstadter, will you marry me?
Penny: Did you seriously just say "Umm..."?
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: Can we talk?
Penny: We can, but the part of "Penny" might get cut.
You didn't get your part cut. You didn't get your part cut. Yep. A bunch of old guys rockinig out in a band, all with erectile dysfunction, you didn't get your part cut!"
Amy: What's the show?
Penny: Um, NC ... II .... Or, you know, NCSTD ... I don't know, it's the one with all the letters and I'm gonna be on it!
