"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-
Not the pox, you foolish blocks,
I mean this very song-
For I was right, and you were wrong!"
"Will!" Charlotte shouted over the noise, "Have you LOST YOUR MIND? CEASE THAT INFERNAL RACKET! Jem-" 
Jem, rising to his feet, clapped his hands over Will's mouth. "Do you promise to be quiet?" he hissed into his friend's ear.
Jem let him go. "All right, then."
Will slid to the floor, his back against the armchair, and threw up his arms. "A demon pox on all your houses!" he announced, and yawned.
"Oh, God, weeks of pox jokes," said Jem. "We're in for it now."
and...
"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." -Infernal Devices

"Life is a book and there are a thousand pages I have not yet read."- Infernal Devices

"They ate it too," Will reminisced. "Bloodthirsty little beasts. Never trust a duck."- Infernal Devices

"It means 'Shadowhunters: Looking Better in Black Than the Widows of our Enemies Since 1234'." -The Mortal Instruments

"Black for hunting through the night
For death and mourning, the color's white.
Gold for a bride in her wedding gown,
And red to call enchantment down.
White silk when our bodies burn,
Blue banners when the lost return.
Flame for the birth of a Nephilim,
And to wash away our sins.
Gray for knowledge best untold,
Bone for those who don't grow old.
Saffron lights the victory march,
Green will mend our broken hearts.
Silver for the demon towers,
And bronze to summon wicked powers." -The Colors
