" Demon pox, oh, demon pox,
Just how is it acquired?
One must go down to the bad part of town
Until one is very tired.
Demon pox, oh, demon pox I had it all along—
No, not the pox, you foolish blocks,
I mean this very song—
For I was right, and you were wrong! "

― Cassandra Clare , Clockwork Prince (The Infernal Devices, #2)
