Buffy the Vampire Slayer, Season 4

Willow:
I'll never get used to this. One day, she's at the friendship ceremony. The next day, she's on the news. The coroner's office said she was missing an ear. So I'm thinking, maybe we're looking for a witch. There's some great spells that work much better with an ear in the mix.

Buffy:
That's one fun little hobby you've got there, Will.

Willow:
Or... or maybe an ear-harvesting demon that--it's, like, building another demon completely out of ears. Or... ooh! Thought. We're just assuming someone else cut off the ear. What if it was self-inflicted, like Van Gogh?

Buffy:
So... she brutally stabs herself, dumped the body, then cut off her own ear?

Willow:
No. She cut off her ear, then killed herself, then dumped the body--I'm really off my game, aren't I?
