The 20 Most Iconic Episodes of "Sex and the City"

Reality had to catch up with a cheating Big and Carrie sometime, and the insane explosion happens in this episode in season three. Natasha accidentally stumbles on Carrie leaving the scene of her affair with Big, and it ends with a broken nose and an even more broken Carrie. She tells Big she can't do this anymore, and we really hope she means it. The show also tackles the really important subject of HIV testing through Samantha's plot line.
