'Charlie: (after leaving a carnation on Kat's desk) I showed you my flower. Now show me yours.
Kat: Leave... me... alone!

(The guys are watching Kat working on her car)
Ray: Twenty says she quits by the end of the day.
Brad: Oh, come on if everyone bets against her, there's no point in having a pool.
Ray: Patrick?
Brad: Do you wanna bet on her?
Patrick: Not while she's anywhere near power-tools.
(Kat looks up and gives them all a dirty look and walks over.)
Kat: I'll bet on myself.
Brad: Careful, that money could buy you a bunch of tampons.
(Brad and Ray bump fists and walk away laughing.)

Bianca Stratford: When I go out, I have to file the flight plans with the FAA. But she gets to go out without questions asked?
Walter Stratford: [to Kat] Gonna drink?
Kat Stratford: No.
Walter Stratford: Drugs?
Kat Stratford: No.
Walter Stratford: Sex?
Kat Stratford: Gross.
Walter Stratford: [to Bianca] Satisfied?

Bianca: Dad, it's healthy for us to spend time apart so we don't get sick of each other.

Bianca: (sees Kat's shirt all wet) Look at you. Maybe you should change your shirt.
Kat: (drunk) Maybe you should change your face! (laughs)

Bianca: Charlie, you and your friends and your friends' friends should tune into BiancaAndDawn.org tonight for some Katy Perry action.

Bianca: (On the phone) Hey Kat, it's your sister calling from a deserted parking lot. (Fakes talking to someone else) Oh, hello creepy man in a van, no I don't need a ride, my sister's picking me up. Thanks. (Turns back to the phone). Call me!

Bianca: (to Patrick) Look! Deep, deep down beneath my sister's crusty exoskeleton, she has a soft spot for you.

Bianca: Do you have keys to any of the classrooms? I NEED you to open one.
Kat: Chastity needs more room for her ego?
Bianca: Someone brought a family into our room and she's a bit territorial.
Kat: Too bad. Tell Gangus Chastity that there's a fire going on and we all need to pull together.
Bianca: Yeah, yeah, yeah- we are the world I get it. Can't you just open a door please?
Kat: Not a chance.
Bianca: Why can't you just help me once? Why does everything you do have to be about principles?
Kat': Why does everything you do have to be about Chastity? It's pathetic.
Bianca: Fine, I guess you'd rather be handing out water bottles to old ladies than making out with Patrick Verona but you're right I'm the one who's pathetic!

Bianca Stratford: I have a big fat favour to ask.
Chastity Church: Uh - I don't respond to fat.
Bianca Stratford: Okay, small skinny favour then.

Bianca: (to Joey about her dad) I'm sorry. He has some sort of disease that makes him cranky. I think it's man-opause.

(Walter arrives at the school auto shop to discover that Kat has disassembled many pieces from her car)
Walter: Why didn't you call me earlier?
Kat: This is a car, not a uterus.

Bianca [to Dawn]: Why can't Brad and Angie adopt us?
Dawn: At least I've got a shot. I'm Asian.

Bianca: Can I borrow your- (Patrick and Kat turn to look at her) A male in your bedroom and he's cute! Am I sleepwalking again? (Patrick smirks while Kat pulls Bianca into the room and closes her door, shushing Bianca)
Kat: (Patrick sits down while Kat freaks out) Dad is going to hear you.
Walter: Girls!
Kat: Oh my god! Crap! Crap! Crap! Get out! Get out! Get out! Get out! (pulls Patrick up from her chair and pushes him towards the window) Just a second Dad I'm...indecent!
Bianca: And in so much trouble. I'm loving this.
Walter: I'm coming in!
(both girls look towards the window, Patrick's gone)

Bianca: But you're gay!
Cameron: I'm not gay! At all! In fact, you're gayer than I am because you kissed a girl.
Bianca: That was for money.
Cameron: See, I could never kiss a guy for money, except for Johnny Depp.
