Donna: What's the big deal? I mean, just because David's a geek doesn't mean his dad is.
Kelly: Donna, the avocado doesn't fall far from the tree.
Donna: No, you know, David's not that bad. I kinda got to know him when we did our scene.
Kelly: I don't know, he's always looking at me like I'm naked or something. And now he's fully bragging about this date like it's the two of us going out.

Donna: You guys, come quick!
Jackie: What?
Donna: It's raining in the living room!

Dylan: Can I say something? I mean, I know the last thing you need right now is another guy telling you what to do or what to think.
Kelly: Go ahead, please.
Dylan: You're blaming yourself for leading that guy on, but I want you to know as a guy it doesn't matter how much of a magnet a girl turns on. A guy always has a choice of not making her do something she doesn't want to do.
Kelly: I didn't make that choice very easy, now did I?
Dylan: Yeah, you did. You said no.

Dylan: Got Kelly fooled. Be careful, Jake. She's a young girl. Emotional. If she feels something, it's permanent record. Trust me, it doesn't feel good to have that messed with.
Jake: Kelly knows what's up.
Dylan: Oh, you told her your life history.
Jake: Hey, don't worry about Kelly. Okay, Dylan?
Season 3

Dylan: Hey, did you bring your guitar?
Emily: Yeah, I did, it's in the living room.
Brandon: Oh, well go get it, we could use some music around here.
Emily: K.
Brenda: Oh great, a hootenanny.
Brandon: Brenda!
Brenda: Oh, excuse me. I didn't mean to be rude.
Emily: Yes, you did. In fact, it seems like you're going out of your way to be rude to me, Brenda.
Brenda: Well Em, why don't you just go get your guitar, and bring it back in here, and we'll all gather 'round and swoon.
Emily: Hey! You're the one that invited me to this party, remember? If you want me to leave, just ask, I'll be happy to oblige.
Brenda: Oh and disappoint your fans? I wouldn't dream of it.
Dylan: Brenda!
Brenda: Dylan, stay out of it. This is between me and Emily.
Emily: Geez! This isn't Beverly Hills, it's Knot's Landing! When I got to school they should have given me a score card instead of a class schedule, so I could keep track of everyone's boyfriends.
Brenda: Oh yeah, like that would have made any difference.
Emily: Oh, grow up, Brenda! You, of all people, should know what it's like to be the new kid in school! All I was trying to do was make friends. I shouldn't have bothered.

Dylan: We better go before the porsche turns into a pumpkin.
Brenda: Do we have to?
Dylan: Yeah, it's either that or you call Jimbo and ask if we can stay down here another week.
Brenda: Ooh, adios Mexico.

Dylan: You can't have it both ways, Bren. The fact of the matter is you gave up any right to ask me questions about my sex life when you decided you didn't want to be a part of it.

Dylan: You got a nice home. A secure family. My mom is a looney tune and my dad is in jail for god's sake!!
Brenda: I know. I can't imagine how that must feel.
Dylan: You're right. You can't. You can't even imagine it. So who are you to come down on me about my negative attitude?
Brenda: Dylan I know you got a bum deal. But can't you look at what you have that is good?
Dylan: Like what?
Brenda: Like your friends. Brandon loves you, all the guys think that you're totally cool. I mean every girl I know would love to go out with you
Dylan: Every girl. But one

Emily: We'll just say we're another couple going as Brandon and Emily. Hey, just think how impressed they'll be with our masks.
Brandon: Well, I'm pretty impressed with your mask already.

Iris: [talking about Hawaii] It's a great place to drop your inhibitions, Jim, you know? Grow a beard, swim naked.
Jim: How...alternative.
Brandon: Oh, come on, Dad, let's do it, let's just drop out for a while.
Cindy: Couple of weeks in Hawaii doesn't sound bad to me right now.
Iris: It is a magical place, you should have seen Dylan when he was there, it even mellowed him out.
Dylan: It didn't mellow me out, I was bored out of my gourd.

Iris: You are a magical young lady.

Jackie: Doesn't that sound fun?
Kelly: No, that sounds totally excruciating.

Kelly: Besides, what cute guy is gonna take an acting class?
Brenda: Kelly, can't you ever stop thinking about guys for one second? I mean, there is more to life!
Kelly: Sounds like it's that time of the month.
Brenda: Well, it is. And it isn't, if you know what I mean.
Kelly: What are you talking about?
Brenda: I'm five days late.

Kelly: Brenda, she said he had a cute scar, what do you think is gonna happen?
Brenda: Kelly, are you gonna do any homework this year?

Kelly: Dylan McKay, that's all we ever talk about! Did it ever occur to you that other people have relationships that they take seriously!?
Brenda: How can you even compare your problems with Jake who you barely even know to my problems with Dylan? I mean, you're not even up there with Donna and David!
Donna: What's that supposed to mean?
Kelly: That means that Brenda's being a self-centered little bitch!
