Kim Cattrall (Samantha) named the scene where Samantha and Richard are dancing on the rooftop one of her favorite scenes of the entire series.
This was the first episode to air after the attacks on September 11th, 2001 but was filmed before the attacks and the World Trade Center could be see in the background of a couple scenes and they had to be digitally edited out.
Carrie: Someone once said that two halves make a whole. And when two halves move in together, it makes a whole lot of stuff.
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!
When Samantha anwers her cellphone, the display reads that it's 07/20/01, then tells Richard that it's Sunday. However, July 20th fell on a Friday in 2001.
