It started when the phone rang.

Dusty Tome looked up from the books he had been stamping and picked up the headset.

"Hello. This is the Fillydelphia Public Library."

"Ah, yes... I, uh, I am looking for a book. It's kind of an emergency. Really bad."

Dusty Tome's mouth creased into a slight frown. "What book are you looking for?"

"From what I understand, it's called Redhoof's Radical Guide for Radical Rituals. It's... kind of important that I find this book as soon as possible."

Dusty's frown deepened ever so slightly. "Sir, that is not a book we have."

"Is there anywhere I can find it?! I've been calling around to various libraries and some of them just laughed me away! I need to find it!"

"Sir, we do not have that book because that book does not exist. To my knowledge, that book title is popular around Celestia's School for Gifted Unicorns as a sort of hazing ritual involving tricking a first year student into trying to find it for one of the older students."

...

"MOTHERFUCKER!!!"
