The Hobbit:
When Bilbo makes it back to the Shire and retrieves the barrow treasure, he finds that all of the treasure's value (which was to have been his pension) was backed by subprime mortgages.
Off he goes on a new quest: this time to the land Tubigtu-Faile, where he sneaks down a tunnel into a bank vault and begins a game of riddles with Ban-Qur, who is lying atop a pile of junk bonds.
"What," asks Bilbo, "is heavier than stone, lighter than a feather, as ephemeral as a maiden's beauty yet as deadly as a viper?"
"My promise to you ..." began the ban-qur (and this, of course, was the correct answer, but he hadn't the wit to shut up)... "My promise to you is that according to the signatories of the second party of the sub-agreement's fourth clause of amendments in reference to that person, persons or entity being either able or unable to redeem the debentures is that you may depend upon me to discover a mutually beneficial compromise from which an annuity shall accrue to the first party ..."
Bilbo had heard enough and cut off his ************** his tongue.
