Heh, would it surprise you that the first thing that popped into my head was Weapons of Class Destruction because of The Kiss? lol Except I don't really like the MOTW for that episode, so it's really ONLY about the kiss.

I think I might have to go with An Echolls Family Christmas for sheer quotability, plus the beginning of the Logan/Veronica thaw and the shocker ending. But I also love the use of unreliable narrators in A Trip to the Dentist (enough that I wrote a whole BtVS fic based on that episode). Hmmm. Dilemma.

What made you start writing fanfic?
