Contessa of Emilie Autumn's Bloody Crumpets likes to see herself as this. Then again, seeing as how the Crumpets are supposed to be a group of asylum inmates, "sane" is relative.
Contessa: I would like to make it very clear that I am not, I repeat, I am not, not, NOT insane!
Everyone Else: (hysterical laughter)
Emilie: (to the audience) ...She eats people!
