Samantha: Carrie, you can't date your fuck buddy.
Carrie: Say it a little louder, I don't think the old lady in the last row heard you.
Samantha: You're going to take the only person in your life that's there purely for sex, no strings attached, and turn him into a human being? Why?
Miranda: You double-booked?
Carrie: How do you conceive pulling this one off?
Charlotte: Early dinner with bachelor number one, late supper with bachelor number two.
Samantha: My god, you're turning into a man!
Carrie: (voiceover) Apparently Charlotte had done more than just break a pattern. She had actually changed genders.
Charlotte: I just don't know how I'm going to eat two dinners in a row.
Carrie: (voiceover) And just like that, she was a woman again.
Carrie: It's a pattern.
Samantha: I don't have a pattern.
Carrie: In math, randomness is considered a pattern.
Samantha: Yes, and I'm what they call a prime number.
Carrie: A fuck buddy is a guy you probably dated once or twice and it didn't really go anywhere, but the sex is so great you sort of... keep him on call.
Samantha: Ooh, he's like dial-a-dick!
