Useful Book

A standard visual gag almost always Played for Laughs.

Alice is looking for something. Maybe it's a new outlook on life, help with a homework problem, or maybe just her pen. Bob hands her a book, or suggests a book he doesn't have with him, and suggests she shouldn't take too long to finish with it, and before she can thank him or object, he's out the door.

Cut to Alice suddenly realizing the book in question is a Door Stopper - and Bob expects her to finish in half an hour. It might be a religious text, a very wordy legal document, a dictionary, an obscure scientific (or arcane magic) textbook, the phone book, a catalog with no index, possibly even a Tome of Eldritch Lore or Great Big Book of Everything - anything that normally would take longer than an hour or so to read through.

Later, it's revealed that Bob actually gave her the book:
 * To stand on to reach something.
 * To sit on, because the chairs are too low.
 * To put under her computer monitor.
 * To use its pages as toilet paper.
 * To prop open a door.
 * To Throw the Book At Them.
 * For use as a Pocket Protector.
 * To give her what's inside it
 * Or some other purpose other than to read it.

For more book-themed humor, see:
 * As the Good Book Says
 * Bookworm
 * Door Stopper
 * Throw the Book At Them.

Compare It May Help You On Your Quest, Magic Feather, and Pocket Protector, where other objects are used for purposes other than for what the audience may have been led to expect. Contrast Reading Is Cool Aesop.

Advertising

 * The Yellow Pages used this at least once, with a small boy standing on a copy to kiss a slightly taller girl.

Film

 * In Evil Dead II, Ash uses Ernest Hemingway's A Farewell to Arms to weigh down his possessed, amputated, killer hand. Give it a second...
 * In Iron Man 2, Tony's SHIELD watchdog uncovers a partially completed red, white and blue shield with a star in the center. Tony exclaims "that's perfect! Just what I need!" and then uses it to prop up the Particle Accelerator he is working on. "Perfectly level," he says, pleased afterward. It should be noted that there are multiple actual books also being used to prop up the particle accelerator. (As well as several of his cars, a motorcycle, and pretty much everything else in his lab.)
 * In Wagons East, a man goes into a bookstore and asks for "a big damn book". The proprietor offers a copy of Pride and Prejudice. The man tears several pages out and makes for the outhouse.
 * In Die Another Day, Q gives James Bond the Door Stopper manual of his new car. Bond throws the book in front of the car, triggering the shotguns under the hood which promptly shoot it to confetti.
 * In Mirror Mask, Books are used as food for sphinxes (as they love to eat the pages, and get distracted by a good book) and to fly on (they return to the library when insulted and thrown with great force). There's also the Really Useful Book, which dispenses good advice but becomes this trope when,.
 * In Without a Clue, a clue requires a Bible. Sherlock Holmes exclaims "I have a Bible!" and runs and gets it out from under one of the legs of his bed.
 * Inverted in Ricochet, where the villain asks for a large bible from the prison reading cart ... to use as a prop to force his shattered knee back into alignment.

Literature
"Nomad: What is it that a man may call the greatest things in life?
 * Brother Oates does this to himself in Carpe Jugulum. He consults his holy book for advice while freezing to death in a downpour, which leads him to realize that what he really needs is kindling.
 * Also, the Door Stopper book How To Kille Insects.
 * Cohen the Barbarian can't read very well, but he thinks a book is always valuable equipment, especially one with thin pages.

Cohen: Hot water, good dentishtry and shoft lavatory paper."

"But perhaps the book had other virtues. Maybe, just maybe, this 1,168 page book could save someone's life if they were being shot at. Just to make one thing clear: I, in no way, advocate the use of fire arms to maliciously deface intelectual property. I wouldn't have tried this on The Scarlet Letter which is 272 pages and which I equally disliked. I was going to shoot The Stand in the name of Science and public safety. The answer is no, my friends. 1,168 pages are not enough to save your life from a .45 slug."
 * Lampshaded by one book reviewer:


 * Averted in The Recruit. James and Kerry find a copy of the Complete Works of Shakespeare in the pack they're expected to carry through a tropical jungle. Naturally they throw it away to save weight, only to later realise that they were supposed to keep at least part of it for use as toilet paper.
 * In Harry Potter, Professor Flitwick, who is very short, frequently sits or stands on top of books so he can see the whole classroom. Though being a Hogwarts professor, he definitely uses books for their intended purpose as well.

Live Action TV
""Dick Cheney's written a memoir of his life, a thousand pages. You can actually use it to stand on to reach a better book."
 * In the Hancocks Half Hour TV episode "The Missing Page", a librarian is impressed when Hancock asks for some weighty intellectual tomes, only to discover that Hancock just wants to stand on the books so he can reach a sleazy crime thriller on the top shelf.
 * Cited recently by David Letterman, three times.

"Sarah Palin has finished her book. It's a big book, over 400 pages. So when you go into the bookstore you can use it to stand on to reach a better book."

And again, with George W Bush's memoir."

""How do they put budgies down?"
 * From Monty Python's Flying Circus:

"Well, it's funny you should ask, because I've been reading a great big book on how to put your budgie down, and apparently you can either hit them with the book, or shoot them just above the beak.""


 * In Home Improvement, Jill mentions that she gave Tim a copy of The Feminine Mystique, but that he uses it to prop up his workbench. Subverted later on, though, when Tim reveals that he did read it (he mis-refers to it as The Feminine Mistake, but the point still stands).
