What is it and why?

Least favorite has to be (not sure I have it exactly right)"Your girl is lovely Hubbell" from that scene in which Carrie is late walking to Big's wedding, spots Big getting into the car and starts quoting from "The way we were". Of course Big didn't have a clue what she was talking about, but it didn't matter to Carrie because she was riding on her epipheny (hello...cucucucucurly!). So Big say's "I don't get it" to which Carrie replies "and you never will" which has to be the second worst line considering the circumstance. That whole scene was painful, but then again it typified Carrie's botched attempts to link with Big (her problem was really her own fault).

How about the one in which Miranda's mom died. It was too sad.

The last episode of the most recent season, in which Aiden and Carrie move in together, and she discovers an engagement ring hidden in his packed clothes. She comes off as greedy and superficial when she decides that she can't marry Aiden because she doesn't like his choice of engagement ring. Also, I can't believe that Miranda is having a baby, and you can read the writing on the wall with Samantha - she's gonna hook up with her new boss. This pretty much takes all four of the girls off the market, and I guess you can figure out the rest...
