Coco Lenoix: Honey, you're a good kid, but what you're telling me is a load of horse puckey. Even though it comes from a good place.
Coco Lenoix: You know, there was a man that lived here once that had a prize-fighting kangaroo. Well, you just wouldn't believe what that kangaroo did to this courtyard.
Betty Elms: It'll be just like in the movies. Pretending to be somebody else.
Betty Elms: I hate you. I hate us both.
Cynthia: Do you know somebody called "the Cowboy"?
Adam Kesher: The Cowboy?
Cynthia: Yeah, the Cowboy. This guy, the Cowboy, wants to see you. Jason said he thought it'd be a good idea.
Adam Kesher: Oh, Jason thought it'd be a good idea for me to see the Cowboy. Well, should I wear my ten-gallon hat and my six-shooters?
Bob Brooker: It's not a contest... the two of them... with themselves... So don't play it for real until it gets real.
Betty Elms: OK.
Cowboy: Hey, pretty girl, time to wake up.
Betty Elms: I'm in love with you.
Rita: Good night, sweet Betty.
Cowboy: Howdy.
Adam Kesher: Howdy to you.
Cowboy: Beautiful evening.
Adam Kesher: Yeah.
Cowboy: Sure wanna thank you for coming all the way up here to see me from that nice little hotel downtown.
Adam Kesher: No problem. What's on your mind?
Cowboy: Well, now. Here's a man who wants to get right down to it. Kind of anxious to get to it, are you?
Adam Kesher: I got the pool, she got the pool-man.
Cowboy: When you see the girl in the picture that was shown to you earlier today, you will say, "this is the girl." The rest of the cast can stay, that's up to you. But the choice for that lead girl is not up to you. Now... you will see me one more time, if you do good. You will see me... two more times, if you do bad. Good night.
Betty Elms: It's strange calling yourself.
Heavy-Set Woman killed By Messing: Something bit me bad.
Cowboy: There's sometimes a buggy. How many drivers does a buggy have?
Adam Kesher: One.
Cowboy: So, let's just say I'm driving this buggy. And, if you fix your attitude, you can ride along with me.
Vincent Darby: I think you're going to enjoy your espresso this time. I've done quite a bit of research, knowing how hard you are to please. This one comes highly recommended.
Answer: Pink colour is sometimes associated with same-sex relationships (eg. the pink stripe on the Bisexual Pride flag is for homosexualism), and lesbian love is one of the main themes in the film. Anyway, David Lynch's imagery is perhaps a little too subtle to be reducible to a code of symbols.
