An interesting case turned up in a commercial for Fruit Gushers that had a space theme. Toward the end of the commercial, some kid's head turns into a flying saucer. At the end of the commercial, we see the kid's Flying Saucer head fly away, leaving his headless body behind.
Could also have some Fridge Horror if you consider the fact that the kid's head might not come back, leaving his body without a head.
In a similar vein, the ad for Gushers Magic Pieces ended with a girl making a candy "disappear," only for her head to vanish in a puff of smoke. Her voice says, "Hey, where'd I go?" suggesting that the head has turned invisible or gone somewhere else. 'Cause, y'know, it's magic.
A terrifying PSA circa 1970 from the Presidential Council on Fitness (?) posited a future where, due to physical inactivity, a man of the time was reduced to a head in a box, carted around by a humanoid robot.

Tom Servo showed during the host segment of this film that he too possessed such a talent.

Fortunately his colleages zoom in just in time to snatch back his head, but not before he's had a horrified moment to realise exactly what just happened. Later Zakalwe is in hospital waiting for a new body to be grown (they gave him the choice of remaining unconscious but he'd rather watch television) when the artificially-intelligent drone Skaffen-Amtiskaw (who doesn't like Zakalwe much, and has a twisted sense of humor) sends him a present. A hat.

In That Hideous Strength, the title of Head of the N.I.C.E. turns out to be horribly literal.

The giant Bolloggs from Walter MoersZamonia novels are unique in Zamonia in that they can survive without their heads; once they reach a certain height they tend to discard their heads — and then go off on wanderings looking for the same heads they just discarded.

Early in Sandman Slim, Stark cuts off the head of Kasabian, the hardest-luck member of the circle that sent him to Hell. He did so with an enchanted knife that only kills when he orders it to, so Kasabian's head sits in his closet for most of the book, bitching about its state. Near the end, it dies outright, only to get sent back by Lucifer as part of a job deal. Between the first book and Kill The Dead, Stark gets it an animated table with articulated legs so that it can move by itself.
One of the historical stories from The Zombie Survival Guide had a tale told to a Jesuit Missionary in Feudal Japan. The story goes that Japan had a secret society whose function was to hunt down and eliminate zombies, and the finial initiation was for an acolyte to spend a full night sitting in a room full of moaning zombie heads that had been cut off and preserved in jars. The "editor" of these historical stories does note that this would be impossible because of the Fridge Logic about the zombies needing lungs to moan, thus either meaning the tale is false, exaggerated, or the moans are the product of the terror felt by the acolytes.
The book also contains several other cases of zombie heads kept in jars, either as part of ancient science experiments or as oddities in various courts.
In a poem by Shel Silverstein, the protagonist complained about losing their head and about the fact that they couldn't look for it ("'cause my eyes are on it"), call to it ("'cause my ears are on it") or even think about it ("'cause my brain is in it") - "so I guess I'll sit down on this rock/and rest for just a minute." (Three guesses what the "rock" was.)

In the Expanded Universe novel Imzadi, Data, decapitated, is still in control of his body.
In another episode of the TV series, Data stepped into a large electrical arc that was blocking a Jeffries tube; his body is non-conductive, so this broke the arc, but he was badly damaged. Riker detached his head, which was still functional, and kept going.

The Headless Monks sometimes do this, keeping living heads around post-decapitation. Since the Monks behead you while you're alive, both the head and the body remain... active. The bodies seem to fall under the control of the other Monks (or possibly the papal mainframe) immediately after beheading. The heads apparently keep the same personality and are left to rot (or be preserved in boxes, if you're rich.)
On an episode where the movie involved a ghostly disembodied head, both bots remove their heads and speak in ghostly voices in an attempt to scare Joel. Unimpressed, he takes their inert bodies away and leaves them alone with the lights off.

Happens in the Good Luck Charlie episode Gabe Turns 12-½ when Bob Duncan goes to the fridge to get some cake in a platter only to find P.J.'s very much alive head instead, which then asks where his body is at (which is never directly explained). Bob then realizes his son's unable to stop him so he eats a cupcake in front of his face. Of course, since it's an end credits gag, this never really happened.

In the game BIONICLE: Heroes, it's a recurring theme, and every boss you defeat (apart from the final boss) is left as just a head at the end of the fight. Rule of Funny applies. There's also an Idle Animation where your character starts playing keepie uppie with its head.
A gag-video released on-line had Hahli Mahri's head popping off due to a rough submarine ride. It falls on her foot, causing much pain.

When standard freezing spells didn't work, Nefrekeptah went for the direct approach and cut off the serpent's head, and threw it far into the river. However, the head came back almost instantly and blocked his path again. Nefrekeptah again cut off its head, threw it into the river, and this time put sand on the neck before the head could come back. The head couldn't reattach, and though the serpent couldn't die, it just lay there, helpless.
In Japanese folklore there are monsters called Nukekubi; they seem like normal humans during the day, but in the night their head detaches from their bodies and starts to float around and search for a human victim to devour.
Similar monsters are recorded in a number of East Asian countries, with perhaps the best-known being the Malaysian penanggalan.
Baba Deep Singh. The legend says that his head was cut completely or almost completely off and still was able to fight.
The Deadlandsincarnation of Joaquin Murrieta died. He came back. Then, he got beheaded. Now, his (understandably insane) body's looking for his head, and is more than happy to "borrow" yours until he finds it. The best part? Undead Joachin Murrieta can only be stopped if you destroy his head. Happy hunting!
Trolls in Dungeons & Dragons; anything cut off them, including heads, can live and will either reattach itself or regenerate.
One of the Mystara supplements described trollish games, some of which involve using the head of one of the participants as a living football. Which tries to bite the feet that kick it.
Unsurprisingly, the Ravenloft setting plays with this trope. Jacqueline Montarri is a headless NPC villain who steals the heads of women to wear, and has an enormous collection of decapitated and still conscious female heads in her basement. (This is a curse, which she can only undo by finding her real head, which she has been looking for ever since she was executed by beheading centuries ago. To be blunt, as she will tell you horrid fates like this will often befall those who cheat and murder members of the Vistani.) Lebendtod, a zombie-like undead template, can remove their heads and limbs at will.
In earlier editions iron golems could continue to function after losing their heads, including breathing out poison gas.
Exalted has an odd version of this from the dangerously powerful Charcoal March of Spiders supernatural martial art. The user delivers a punch so ludicrously hard that the head not only explodes, but the person whose head did explode has several seconds thereafter to think and react because they, and reality itself, haven't caught up to the fact just yet.
In GURPS 3rd Edition, one of the supplements full of fantasy magic spells had a spell called Decapitate, which did exactly what its name says. Not only that, both the head and body were still alive, and since the head was still magically able to speak, if it knew any spells, it could still cast them! Of course, without the head, the body could not eat or drink, and would eventually die of dehydration or starvation. But this was not a problem either! Another spell allowed you to turn everything BUT the head into stone... and THEN you could decapitate him.
The Orks of Warhammer 40,000 are so tough that their decapitated heads can survive for up to an hour, more than enough time for a Mad Dok to easily attach it to a new body or just staple it back on.
In Pippin, Pippin has a poignant conversation with the head of a fallen Visigoth soldier. In a later scene, after Pippin has been crowned king, a headless man comes up to him and asks for his head to be reattached.
In a Ravenloft skit performed at GenCon 1999, "One Piece At A Time", a lady surgeon attempts to bring her fiancee back to life after he dies in a tragic accident. The title says it all, but early scenes correspond to this trope.
Jenova was decapitated in the events leading to Final Fantasy VII. Sephiroth, realizing the jig is up (and unable to take the entire body with him), removed his "mother's" head on his way out of the Nibelheim mako reactor. However, he was waylaid by pre-amnesiac Cloud Strife and thrown from the connecting bridge, sinking into the pool of mako. The headless body of Jenova continues to live on - albeit in cryogenic suspension - waiting to be "reunited" with its missing parts.
In Primal, the Wraith can apparently survive being decapitated. A group of severed heads in Raum's torture chamber (all of whom hate each other) eventually take time out from arguing to help the PCs. One, however, calls the guards, simply to antagonize the rest.
Other severed heads are scattered almost randomly throughout the upper mansion, giving comments, advice, and encouragement. One somehow knows Scree's name.
In Chrono Cross one skeleton character, which you have to assemble, starts off as a talking skull.
In Resident Evil 3: Nemesis, when you fight Nemesis in the Treatment Room. Douse him with a remarkable strong acid two times and his head will come off. But rather than die like the zombies, he continues attacking, albiet blind.
Killer7 has Susie, a severed head you tend to meet in very enclosed spaces (the first one being a washing machine). She always has a ring in her mouth when you find her. She's also a ghost. She's also completely loopy.
Murray the Talking Skull in The Curse of Monkey Island. Justified in that he was actually dead and re-animated by spooky voodoo magic well before he became a disembodied skull.
In Animamundi Dark Alchemist: The hero's little sister was beheaded, but still survived. Granted, by the game's universe rules, it was part of a "Test" - only witches can survive beheading.
A head in a jar is a "work of art" that you can purchase in the console version of The Sims.
Boomer in Ballz throws his head as a special attack.
Tekken 6 has Alisa Boskonovitch who can remove her head and have it explode in front of her opponent. Of course, a new one emerges shortly after.
Kratos in the God of War games not only is able to tear off the head of the Gorgons, but proceed to use their (apparently still living) heads as weapons, petrifying enemies with their eye-beams. In the third game he does the same for the god Helios, using him as a Lantern.
The Recapitator (skeleton enemies) in Wario Land The Shake Dimension have their sole attack being to detach and throw their head at Wario like a boomerang, catching it afterwards. They also come back to life when killed like the Dry Bones in the main Mario games, and can only permanently be killed by destroying their body while their head is in mid air. Or, if you're feeling saucy, destroy the head and leave the body hanging for awhile before it collapses into a heap.
PS1 RPG Shadow Madness had a disembodied telekinetic head by the name of Xero von Moon. He was kept alive (and presumably afloat and able to speak) by a thin metal ring at his neck, and fought primarily with kinetic bolts (though he could resort to a headbutt).
Although very loosely, Dynamite Headdy surely counts as the main character throws his head around and switches it with power-ups. Not to mention it explodes when he dies and it gets replaced with a game over sign.
The main character of Never Dead, a game about an immortal gunslinger fighting a demonic invasion. Even if dismembered, he can put himself back together again. He loses his head (both figuratively and literally) in the first trailer. "My story was just getting interesting too!"
In Vampire Savior, Jedah has a move called Spregio that has him doing this to himself and blasting the opponent with the resulting rush of blood!
A straighter example would be the Final Boss of Darius Force, Galst Vic (a Terminator-esque robot). When his first form is defeated, you have to escape the exploding base... and then his head comes to attack you! Strangely enough, his head can grow◊ and shrink◊ in size.
The player character in The Incredible Crash Dummies can lose his head, resulting in reversed controls until you find a spare head.
The boss Echizen in Death Crimson OX has a head that I can only describe as an egg with a pair of giant red lips. Part one of the boss fight is fighting his kung-fu kicking body as his head continuously inflates. Part two involves his head floating off of his body, then splitting into six individual floating heads that then proceed to ram into you and shoot lasers at you.
While inversions are also more common, in The Binding of Isaac, Pestilence and sometimes Gapers and Mr. Maws continue moving after losing their head.
Pictured above is a scene from a Team Fortress 2 promotional video. The head of the BLU Spy, which the RED Medic keeps in his fridge, is being sustained by some eldritch and surely illegal medical technique involving dry-cell batteries.
Skullgirls has Ms. Fortune, an undead catgirl who was chopped up into pieces by the mob after stealing and swallowing a gem that made her body undying. Her fighting style revolves around extending, detaching, and reattaching her limbs — most notably her head, which functions not only as a weapon but is capable of propelling itself around and attacking independently of her body.
In Lollipop Chainsaw, after Nick is bitten by a zombie Juliet decides to save him by chopping off his head and preserving it with a magic ritual of some sort. He's not exactly happy about the situation but Juliet thinks that it is just awesome that her boyfriend is now a talking head.
In the "Test Your Luck" game in Mortal Kombat 9, one of the results causes both fighters to fight the next match headless. The worst thing about this is, neither player can use X-Ray moves; exactly how bad it is otherwise depends on what fighter you're using. (For many, it's not much else, but for a few, it can be very hindering. It's the most debilitating for Kung-Lao, seeing as half his moves and almost all his Fatalities require his hat.)
In Grim Fandango, Salvador Limones gets reduced to a talking skull. Sure, he was Dead to Begin With, but the rest of the skeleton, which you have to find later, is not animated, implying that the head is still the part that holds one's consciousness, even after death. Even as a skull, Sal manages to perform a Heroic Sacrifice by spitting Sproutella into the face of a character who betrayed him, thus rendering both of them Deader than Dead.
The Witch Doctor in Adventure Island loses his head each time you defeat him, only to have it replaced by an uglier mug.

An encounter in the residential area has a character get his head knocked off by a passing truck. The head starts directing the body to try and pick it up.
"Hey, I'm over here! To my left! Er, your left! Er, our left!" (body walks towards head) "Right." (body goes right) "Not 'go right,' 'correct'!" (body kicks head) "It's not a soccer game! Use your brain! Oh, I guess ... that's over here." (body kicks head again) "Ow! Just bend down slowly and—" (body kicks head high into the air and it lands on the neck) "He shoots, he scores! OW!"
In Ogre Battle, you can recruit Pumpkins (men with pumpkins for heads) into your army, who attack by tearing off their own heads, kicking them into the air, whereupon they grow to huge size and land on an enemy, halving their HP (or killing undead units outright) unless they miss. If you upgrade them to a Hallowe'en, they can do it twice a fight!
In Office Zombie, you can cut the Zombie's head off with a couple of items. When you throw it back, he'll stick it back on his neck and be good as new.
Happened in Bite Me! via guillotine; her head was later located by the main character being asked to list head puns (in a room full of severed heads) until she groaned loudly enough to be found.
An entire storyline of Narbonic revolves around how Dave's disembodied head is forgotten on the bus.
Probably the single most infamous comic from Sexy Losers involved Shiunji, a necrophiliac, a corpse whose head fell off, and what he did to its neck. The comic's subtitle read "I am certain that at some point in the future, I will be prosecuted for this comic in a court of law."
In Looking for Group, one of the men in Richard's village. Justified because he's not exactly human...
Also, Richard is beheaded but still able to maintain his normal levels of awesome.
Stubble Trouble features the decapitated characters of Gynette the spidertaur and Lilith the Headless Goth Vixen. Gynette's boyfriend really seems to like her ability and her friends are unfazed as she often takes her head off. Lilith the Headless Goth Vixen was a former model who was famous for her decapitation.
Done in Khatru, where Healing Factor powered Ranger unwittingly agrees to test one of Gadgeteer Genius Kira's medical scanning devices. She tries everything to fix him, but in the end, he recovers all on his own.

Castle Heterodyne while its mind was stored in the body of Otilia.
Doctor Sun keeps Selnikov's head in a jar, preserved and conscious for interrogation.
In the Girls in Space storyline The Protoype, Fergus Macrumble punches the Henchbot's head off.
Runcible Spoon in Dominic Deegan is known for sending his own head flying. Also once happened to Quilt, including the "hey, body, over here" routine.

Gary from Nintendo Week begins hosting one episode as a disembodied head, with his body stumbling into walls in the background. He promptly explains this is a nod to Face Raiders for the 3DS.
Web Serial Novel
GR-210 is reduced to just a head in Statless And Tactless when he horrifically fails an attack roll and the GM is feeling vindictive. However, being a robot he's still alive as a head and gets carried around in a backpack.
Kevin Spencer fantazises about this in one episode: he imagines himself living in an old age home as a head, refusing to die. The staff decide to just run him over with a car. This trope is played with in the final episode, with Percy.
Bender also suffered this, at least once as a Shout-Out to Star Trek: The Next Generation. In another instance, he purposely sells his body for lots of money (it was worth more due to supply and demand). He drove around in a little car until getting it back from President Nixon. He also uses his ability to detach his head to (what else?) rob people.
And in Bender's Game Zoidberg's head crawls on tentacles once it's been severed from his body. Since that instance took place in Bender's fantasy world it's not certain if the real Zoidberg can do it as well.
As well as Hermes in the Futurama movie, Bender's Big Score. Somehow he managed to keep yelling at people for several minutes after being decapitated, before he was put in a jar.
In a Valentine's Day episode, Fry had his head surgically removed and placed on Amy's shoulder after being severely injured in a car accident.
Megatron, Bulkhead, Sentinel Prime, Starscream and Waspinator have all suffered from this in Transformers Animated.
As did Optimus Prime in Transformers Generation 1. Unicron gets reduced to a head after his body is blown up, and he's incredibly dangerous whenever he regains consciousness.
Also happens with Arcee shortly after becoming a Headmaster in the American series finale.
And Waspinator in Beast Wars, several times. In fact, numerous characters, primarily Predacons, end up in pieces, including an intact head. Silverbolt is the only Maximal who suffered this indignity while serving as a Maximal.
In a particularly bizarre episode of Legion of Super Heroes, on their way to Find the Cure, Brainiac 5's head is separated from his body by a Portal Cut; the body then proceeds to run amok while the frustrated Legionnaires try to recapture it.
Arthur "Meek for A Week" Arthur and his friends imagine Francine, who has recently taken to bottling up her natural aggression, will build up enough pressure that her head will pop off.

Similarly, a different episode had Buster's head fly away instead, only his head broke into pieces upon landing.
The Batman "The Joining" Part 1, Batman and J'Onn J'Onzz are able to interrogate the decapitated head of Lucius Fox's robot duplicate. "In order to nod you need a neck"
Homer's costume (which becomes real) in The Simpsons "Treehouse of Horror XVI."
In "Treehouse of Horror IV", he was decapitated while spending a day in Hell.
Oswald the Lucky Rabbit demonstrated the ability to attach and detach his head at will, with no justification other than the Rule of Funny. It is unclear how well he could function headless, as in two cases his head didn't get very far, and in the third he was reassembled by outside means. A post-Disney short indicated other characters in the setting could do this too.
SWAT Kats had this in the episode "Metal Urgency": the Metallikats were reduced to heads scuttling around on spider legs after their bodies were crushed. This doesn't prevent them from driving the Metallikat Express or operating a pair of gigantic combat robots.
An episode of Jimmy Two-Shoes featured a gingerbread man that gets eaten within a few seconds of screentime. The consumer spits out the head, who warns Jimmy to stay away.
An earlier episode has Jimmy ending up like this thanks to some Hollywood Voodoo.
Happens to Heloise in the episode "Heads Will Roll."
In the Larry episode of Teen Titans ("Fractured"), Starfire briefly gets little wings grown on her head, and she needs to hold onto her head to avoid it flying away.

Courage the Cowardly Dog had, among its multiple ghosts, ghouls and monsters, a group of ghostly skeleton vandals who would try to lay waste to the couple and their dog whenever their windmill stopped turning. Hilarity Ensues when Courage, Eustace and Muriel have their heads chopped off by the Windmill Vandals' weapons (with their headless bodies frantically feeling around for their lost heads) and end up on each other's bodies. Courage's head (transplanted on Muriel's body) even uses Eustace's complaining head as a bowlingball to momentarily topple the marauders.
Moreover, this isn't the first time Eustace has lost his head. In an earlier episode, a space chicken that Courage defeated and left featherless and headless in the pilot episode returned to replace its missing head by using Courage's head as a replacement. It only partially succeeds with its plan, taking Eustace's head instead. Although defeated, the head never returns to its original body (at least until the next episode), culminating with the appearance of a headless walking Eustace that scares Courage.
The Canadian short Land of the Heads where a headless vampiress forces his husband to go out into the village and collect the heads of younger people to replace her old and wrinkled one.
It happened to Beetlejuice several times in the animated series, perhaps most unfortunately when he fell in with a group of headhunters. (In one episode, this actually caused his head and body to argue with each other, his body doing so by forming a mouth with its hand.)
An episode of the 1980s version of Flash Gordon featured a race of aliens that could remove their heads.
A cutaway gag on Family Guy has Stewie meeting a woman's best friend whom she claims is hot. Said woman comes by holding her severed head.
Metalocalypse - Mashed Potato Johnson, the oldest living blues guitarist, educates Deathklok on the music - he relates several gruesome stories on the origins of songs, including one Shorty Johnnytop, who made a deal with the Devil and was hit by a train - "...as his head traveled in the air, he wrote 'Blue Train Blues'."
A series of controversial experiments (sorry, we can't tell you when, where or by whom) showed that it is possible to transplant a monkey's head onto a different monkey's body, although establishing spinal communication between the two was not possible. Originally proposed by the surgeon as a means of prolonging the lives of quadraplegics whose own bodies are failing, this technique has been soundly rejected by bioethicists ... not because it's gruesome, but because donor organs can save more lives if they're distributed among many transplant patients, rather than the whole body being used to aid one.
Cockroaches can live for weeks after decapitation. They will eventually starve to death because they can't eat without their mouth.
Back in the days where Losing Your Head was a punny way of saying "capital punishment", some curious people (again, we can't tell you who or when) did a series of experiments which basically consisted of waiting until the next execution, then shouting at the head to see whether and for how long they could keep its attention. The head can stay conscious for 10 seconds or so, though most lost consciousness instantly due to shock. We can thank the French for this information, since they kept using the guillotine for executions until the 20th century.
Internal decapitation, in which the skull is forcibly separated from the spinal column but the soft tissues of the neck remain intact, can be survivable if the injured person receives artificial respiration and other care. If the spinal cord isn't broken, a full recovery is also possible.
A male preying mantis can survive for a short time after decapitation. The female has a tendency to bite his head off, and this feature allows the male to finish mating before he dies.
