Carrie Bradshaw
In the two-part episode "Dick'll Take Manhattan" from season six, in which Dick, Harry and Sally enter into an alternate reality, an alternate universe Sally writes a sex column for the newspaper (an homage to the Carrie Bradshaw character from the HBO comedy series "Sex and the City"). She finds out that she is still dating Don, who is now the Mayor of New York City. However, it turns out that he's actually just having an affair with her.
