So after I'm through reading the latest trash, suspense, romance, life changing, sleeping pill, of a paperback. What should I do with it?

-Leave it in the room(bet it gets thrown away)
-throw it off the 39th floor balcony
-have a funeral pyre
-leave it in the Regency club, bar, gym for someone to pick up
-give it to the front desk
-mail it back home
-put my name and address in the cover, with the words-If found please mail to.(let someone else pay the postage)
-hand it to a complete stranger, tell em what a great read it was and how much they'll enjoy the surprise ending(of course tell em what that ending is)

No where I stay seems to have an exchange library, What do you all do with them?
