Samantha: Have you all had an AIDS test?
Carrie: Good morning, where did that come from?
Samantha: I just met this very hot guy and he won't sleep with me, unless I have a test.
Charlotte: Samantha, we're looking at wedding gowns, could you please not talk about AIDS right now?
Carrie: Wait, you've never had an HIV test?
Samantha: No! Have you?
Miranda: Three. How can you not have had an AIDS test?
Carrie: She doesn't mean that the way it sounds. It's just that, well, why not, sweetie?
Samantha: I always practice safe sex.
(Carrie stares at her)
Samantha: Alright, I'm terrified. What if I have it?
Carrie: You don't have it.
Samantha: Sometimes, it takes me a really long time to get over a cold.
Carrie: That's not AIDS, that's central air.
