Sleeping Dummy

A character wants to sneak somewhere at night without being caught, so he or she stuffs the bed with rolled up sheets or pillowcases or something to make it look as though he or she is still in bed, maybe with a fake papier-maché head sticking out from the sheets. Sometimes it works, sometimes it doesn't.

Bonus points if they use a tape recorder to add breathing/snoring.

One of The Oldest Tricks in The Book.

 * The Invisible Man does this in volume two of League of Extraordinary Gentlemen in order to
 * Surprisingly, played utterly straight in the ultra-gritty Batman story "Troika: Dark Rider": Two Ukrainian gangsters open fire on what they believe to be the body of the Dark Rider (who has defected from his underworld allies to become a Dirty Commie). They instead discover that they have just machine-gunned a stack of pillows covered by a bedspread, and are still standing in shock when the real Dark Rider appears from around a corner and shoots them both in the head.
 * This is a favourite tactic of Jonah Hex, and has saved his life on countless occassions.

Film

 * The Cabinet of Dr. Caligari is possibly the Trope Codifier, if not Trope Maker or Ur Example.
 * Escape from Alcatraz is both a major film example and Truth in Television. The Guards Must Be Crazy!
 * Also subverted in the same film, when a guard reaches through the bars to rouse the figure in the bed and it turns out to be the real prisoner, not his plaster dummy-head.
 * In Ferris Buellers Day Off, this is elaborate to the point of being kinda silly; it includes a soundtrack of him snoring and a pulley system to make the dummy appear to react when the bedroom door is opened.
 * Hogarth, in The Iron Giant, escapes an amoral government agent by doing this.
 * In the movie version of Dr. No, James Bond uses this to trick an assassin into emptying his gun into the bed, leaving him defenseless.
 * Discussed in The Man with the Golden Gun. When Mary Goodnight is hiding under the covers, James Bond tells Andrea Anders that he was using the Sleeping Dummy trick.

 * Aragorn helps the Hobbits with this in Bree.
 * Airplane! 2: The Sequel. Ted Stryker leaves one behind when he escapes from the insane asylum.
 * Used for comedy in Naked Gun 33 1/3: The Final Insult, where the dummies of Rocko and Slasher are so obviously fake that only a bunch of idiots would fall for the trick (which, of course, they do).

Literature

 * The Famous Five.
 * The Bible: 1 Samuel 19:11-16, making this Older Than Feudalism.
 * Used in Lord of the Rings by the Hobbits.
 * Done many, many times by the Animorphs. It helps that (with the exception of Tobias and Ax) their parents actually trusted them.
 * In AA Milne's The Red House Mystery, Anthony and Bill do this before going off to tail a suspect at night, so that the suspect (who is staying in the same house as they are) won't realize they're onto him. Bill is pretty proud of his sleeping dummy, but Anthony's is so convincing that it even fools Bill.
 * In one of the Doubled Edge novels, Rhoslyn needs to go Underhill while seeming to stay in the mortal world. She arranges a couple pillows under her blanket ... and then casts an illusion of her sleeping mortal disguise on the pillows.

Live-Action TV

 * Malcolm in the Middle.
 * Lampshaded in Charmed (The One With... the attempt to frame Prue at the auction house).
 * The Fresh Prince of Bel-Air: Parodied when Philip's elderly mother and Will were sneaking out. Philip's mother suggested stuffing the bed, but Will explained that these days we do things electronically, and played a recording of snoring.
 * Played straight, since Will does use sneakers, pillows and a bust of King Tut to stuff his bed. The snoring tape was just the icing on the cake.
 * Dexter.
 * Subverted in a prime time spy show that aired on FOX around ten years ago. (name, anyone?) The spy and his girl-of-the-week were in a hotel room that the bad guys were closing in on. The baddies break in, and see two big lumps on the bed. The leader scoffs at the use of such an old ploy, and shoots up the closet. The baddies leave...and the protagonists throw off the blankets and get up from the bed. They were counting on the enemy to assume they were just pillows.
 * Mr. Bean did this once so he was at the front of the line for the big New Year's sale.
 * Arrested Development. Buster, not wanting to disturb his mother with his snoring, puts a bunch of pillows in his bed and covers them with his sheets. He also puts a very loud recording of his snoring in with them. His mother, agitated with the loud snoring, starts beating the fake-Buster with a broomstick, eventually realizing that it's a fake. Riding on her luckiness, she decides to go out to try to find any family member in the car. Halfway to her destination, Buster starts snoring from the back seat.
 * Mary Ann from The Baby Sitters Club tries this at camp, using a cantaloupe as the head. It doesn't fool the counselors whatsoever, though she does impress the other counselors-in-training, which was was what she was trying to do in the first place.
 * Used in Supernatural by Sam and Dean. With blow up dolls.
 * In The Rockford Files, Jim Rockford used a variation of this to escape from jail. First he repeatedly told the officer guarding the jail that he would escape and do it easily.
 * Used in one of the prime-time soaps (Falconcrest?) a decade or two ago. A man tried to murder his boss, firing several shots into the lump on the bed. Then the "victim" walked into the room, accompanied by guards, and before the guards dragged the would-be killer away, the boss mocked him by "praising" his shooting: "That cushion's a goner."
 * Done in the second season premiere of Covert Affairs when Ben and Annie narrowly escape some assassins in a hospital.
 * The Doctor and Jo pull this off to help The Doctor escape from imprisonment by The Master in Frontier in Space..
 * Rex does this to convince the others his mother is in the console in the Pixelface episode "Mrs Dynamo's Son".

Newspaper Comics

 * Calvin of Calvin and Hobbes does this, with a broom to mimic Calvin's hair.
 * Appears in The Far Side, where gecko assassins trying to kill another gecko in his sleep, only to find that it was just his tail in the bed. "Idiots! You fell for the oldest trick in the book!"

Videogames

 * Sherlock Holmes uses this gimmick to sneak around the asylum in The Awakened, leaving  arranged like a sleeping figure in his cell.

Web Originals

 * In the Lonelygirl15 video "I'm Going to the Party!", Bree attempts to fool her parents this way.
 * "A fluffed pillow? Impossible!"
 * "It's f*** -ing foolproof!"

Webcomics

 * They do this all the time in A Modest Destiny, and it isn't even to stand in for sleeping people!
 * The cast of Eight Bit Theater does this to escape an assassination attempt... only instead of pillows they sneak over to a camping site, kill several campers and stick their corpses in the beds. On the other hand, pillows don't bleed when cut.
 * To be fair, neither do corpses.

Western Animation

 * In Avatar: The Last Airbender, Katara stuffs her sleeping bag with grass in order to sneak away from the group and engage in a little secret factory sabotage.
 * The Simpsons: Lisa puts a miniature Statue of Liberty head in her bed to fool Marge.
 * Homer has also done this on multiple occasions. In an odd form, he does this at work, but at the same time he's normally asleep at work anyway.
 * Also, the dummies are normally blatantly obvious (A mop with a painted bucket with a recorded message), yet seem to actually work.
 * This latter characteristic was subverted in an episode when we see a perfect duplicate of Bart sitting still reading in class despite also being talking to Lisa in the hallway. "It's a shop class project. It's made of latex"
 * Played straight and subverted in a King of the Hill episode: Bobby sneaks out of the house, leaving behind a sleeping dummy that Hank finds. Hank runs into Luanne's room, assumes the lump in her bed to be another dummy, and pulls the covers back to reveal... Luanne and her boyfriend.
 * Jimmy Neutron does it on occasion, but being a boy genius with seemingly unlimited resources, he has a full holographic representation of himself in bed. And it doesn't work.
 * An episode of Family Guy has Peter doing this to sneak out from under the nose of his wife, Lois. When she goes to check on him, the dummy speaks to her, courtesy of a tape recording Peter made of himself responding to the comments he predicts Lois will make. The ruse works surprisingly well at first, but after a few exchanges, his "answers" no longer sync up, prompting Lois to pull back the bedsheet and reveal the dummy. Of course, at that moment Peter's stupidity ruins the charade anyway: "Lois, if you still haven't discovered I'm gone, please flip the tape over to side B."
 * In Chip 'n Dale Rescue Rangers, "Adventures in Squirrelsitting", Tammy stuffed her bed to forestall, if only for a few moments, Chip's discovery that she wasn't there, and had gone off to Fat Cat's Casino to retrieve the Maltese Mouse, figuring she could prove something if she did it herself.
 * Jenny does this in an episode of My Life as a Teenage Robot. And as a robot, naturally she stuffs the sheets with.
 * In The Penguins of Madagascar short "Christmas Caper", Private uses a bowling pin as a dummy. When Skipper discovers it, he slaps and interrogates it.
 * In the Donald Duck Wartime Cartoon "The Old Army Game", Donald and a few of his fellow soldiers use dummies to fool Sargeant Pete while they go AWOL.

Real Life

 * This has been done for more than one jailbreak. The three convicts who escaped from Alcatraz in 1962 went whole hog and made the papier-mache head. Ted Bundy did this in his second escape, and it worked so well that the guards didn't check until noon, by which time he'd already made it to the Denver airport and flown to Chicago.
