Buffy: Doppelgangland

Buffy: "So you want to go out tonight?"Willow: "Strangely, I feel like staying at home. And doing my homework. And flossing. And dying a virgin." Evil double plots are done to death, but they can be marvelous when they're done well. And this one was done exceptionally well. It was very clever and very funny, with one liners coming thick and fast and everyone wonderfully in character.
