Sometimes, when someone is locked in a closet or Bound and Gagged, it's not for ransom or use as a hostage or some other practical concern, but instead merely as a mean prank, or to get someone out of the way. The poor victim is left behind and... what's going to happen to them? Are they being left behind to die, or are they left out in a public place where they'll clearly be rescued? Are they knowingly being left where no-one will rescue them, or did the captor take that into account? For that matter, did the captor just leave them somewhere and then forget about them?
This trope is sometimes the result of bullying or a prank. It's often Played for Laughs when it's done by the heroes or to an annoying or intentionally dislikeable character. Other times, it's Played for Drama, with tragic consequences. And sometimes it's done for dark humor.
Often crosses over with Something We Forgot, in which the victim is left somewhere intentionally but for longer than their captor intended.
- Happens fairly regularly in Empowered, whose lead character gets absolutely no respect from her peers. One time, she even manages to single-handedly rescue the entire team by driving an SUV into the baddie while all tied up, and the team still wanders off, leaving her trapped behind the wheel.

- MouseHunt plays this for dark humor. It's stated early in the movie that the previous owner of the house with a mouse in it was found dead, locked in a trunk in the attic. Later, an exterminator is hired, and he is later rescued by people who heard his screams and called 911. It's stated he was found locked in a trunk in the attic.
- In the Saw movies, any trap that doesn't kill you outright will do this to you instead.

- At the end of Trading Places, as Randolph Duke is being wheeled past Winthorpe and Valentine, he yells, "Where in hell is Beeks?" "Beeks!" Winthorpe muses. "Yeah, I forgot all about that guy!" Cut to a cage being loaded onto a ship bound for Africa, containing the amorous gorilla and Beeks, who's still in the ape costume Winthorpe and Valentine put him in when they locked him in the cage.
- At the end of The Pit and the Pendulum, Nicholas' wife Elizabeth is left locked in an iron maiden. The only person who knew she was there is dead and everyone else thinks she is dead, so the survivors turn out the lights and seal up the dungeon forever. The last thing we see before the Fade to Black is a close-up of her terrified eyes peering through the tiny slot in the face of her prison. It's OK, though, because she deserved it after deliberately driving her husband insane. Just try not to think about the fact that she's going to die slowly from starvation and/or dehydration...
- In The Silmarillion, Maedhros is Chained to a Rock by his right wrist. He is just left there for many years by Morgoth. When his cousin shows up he begs for death, but is freed when his cousin cuts off his hand. Referenced in the Blind Guardian song "Blood Tears".

- One episode of the original CSI featured a former Jerk Jock, who turned out to have been killed by another student he once left duct taped up in a locker (the result being that he was left with scars from removing the duct tape and ended up in hospital for so long he had to drop out of high school, essentially ruining his life).
- The Dukes of Hazzard had an episode where Bo and Luke escaped from the Hazzard Jail by handcuffing Enos' hands to a chair (arms crossed) and gagged, then hung the chair on a coat rack mounted to the wall.

- Played for mean-spirited humor in The Legend of Zelda: The Wind Waker. Tetra and her band of pirates rob a rude bomb store owner and steal all his bombs, leaving him Bound and Gagged, which you the player witness before the pirates leave. He struggles infinitely as long as the player is still there, and it's impossible for the player to free him. However, when you eventually visit him again, not only is he free, but he is much more well mannered and his prices become reasonable.
- Before a drinking game in the iPhone app "Roommates Visual Novel", the character Dominic is tied to a chair so he can't interfere with the partying.

- When Bruno considers a kidnap-and-ransom scheme in Bruno the Bandit he remembers the last time he tried it. Several years ago. And forgot about the kidnap victim.
- In Sunstone, during one of Ally and Alan's early sessions, a bad burrito on Alan's part and a blown out fuse conspired to leave Ally alone and tied up for forty minutes that were utterly agonizing for both her and Alan.

- In Avatar: The Last Airbender, Toph escapes from a metal box by spontaneously metalbending, then traps her captors inside.

- The Simpsons, "Whacking Day": Bart and a few other low-achieving Springfield Elementary students are locked in a basement utility room to keep them out of the way during a "surprise" visit from Superintendent Chalmers. Bart escapes and causes havoc. At the end of the episode—several days (if not weeks) later—Principal Skinner realizes the others are still locked up down there. They all survived because they were locked up with boxes of food, but Skinner was ready to Run for the Border in case they hadn't.
- In the King of the Hill episode "Soldier Of Misfortune", Hank, Bill, and Boomhauer have been captured by Dale's rival Mad Dog and he leaves them tied up in a back room.

- One scene of the Doctor Who-episode "Mark of the Rani" required the Doctor (Colin Baker) to be tied to a large pole in order to pull off a Tribal Carry. Because Baker wore a difficult support harness to take the strain off his wrists, it was impossible to untie him in-between takes, so they just laid him on the ground when the cameras weren't rolling. However, due to rapidly fluctuating weather, the team had to quickly move every time it started raining to film a different scene set in the rain. During one such move, Baker noticed the team packing up, but didn't realize they'd forgotten to bring him along until they were already out of earshot. It took half an hour for someone to realize he'd been left behind and to come get him.
- Baker told this story in the DVD-commentary of "Mark of the Rani". He also said that, because the filming took place in a public forest, he was found after ten minutes by a couple and their dog. But because the couple had never heard of Doctor Who and didn't recognize him, the absurdity of the situation led them to just leave him there.
- Two of Belgian pedophile Marc Dutroux's victims had died because he was incarcerated for car theft, and they starved to death while being kept captive on one of his properties. The worst part: a detective went to search the property and was alerted to the sound of screaming children by a colleague, but he mistook it as children playing in the street and unwittingly left them there.
