“Demon pox. There's always demon pox.”

“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!”

“Will: Have you ever seen what happens to someone with demon pox? First it lies dormant. One begins to turn yellow and green. Then the swelling sets in -Jem: THERE IS NO SUCH THING AS DEMON POX.”

“Astriola. That IS demon pox. You had evidence that demon pox existed and you didnt mention it to me! Et tu, Brute!' He rolled up the paper and hit Jem over the head with it.”

“And maybe it would have bitten you in half," said Will. "What you are describing, the transformation into a demon, is the last stage of the pox.""Will!" Charlotte threw up her hands. "Why didn't you say so?""You know, the books on demon pox are in the library," Will said with an injured tone. "I wasn't preventing anyone from reading them.""Yes, but if Benedict was going to turn into an enormous serpent, you'd think you could at least have mentioned it," said Charlotte. "As a matter of general interest.”
