Miranda: I don't know ... is it okay to fuck one guy when you're pregnant with another guy's baby?
Carrie: If one more person asks me that today ...
Samantha: This is why I've never lived with a man. This and the fact I want them out an hour after I climax.
Miranda: You let them stay a whole hour?
Samantha: Okay, you want details? Okay. He's got the most perfect dick I've ever seen. Long, pink, amazing. It's dickalicious!
Carrie: I used to think those people who sat alone at Starbucks writing on their laptops were pretentious posers. Now I know: They are people who have recently moved in wtih someone.
Charlotte: Don't talk to my friends like that! Without a baby they're all I have!
Trey: And what am I?!
Charlotte: You are the man who gave me a cardboard baby!
