The Hero is on the ropes, getting his butt kicked by the villain. In desperation, the hero pulls out a weapon and hurls it.
He misses! Or maybe the villain dodges. Either way, the bad guy smirks or laughs at this futile final act of defiance as he closes for the kill...
... only to have the thrown weapon come back and hit him from behind, knocking him out or even killing him. Turns out, the weapon was in fact a Precision-Guided Boomerang (sometimes obviously so), or had boomerang-like properties.
A comedic variant is for the character hit to be also the one throwing the weapon away, believing to get rid of it. Of course, it is extremely unlikely for a boomerang thrown by someone not knowing what it is to actually come back, but this takes a backseat to the Rule of Funny.

- Not exactly a boomerang, but in YuYu Hakusho, in a last ditch effort to beat Hiei, Yusuke goad him into the path of a point blank Reigun shot. It would have hit any other opponent, but Hiei manages to use his extreme speed to get out of the way. He then takes the time to gloat about how Yusuke was almost good enough, only to be hit in the back by the return shot a few seconds later; as it turns out, Yusuke figured Hiei would dodge, so he positioned himself so the shot would hit the Mirror of Darkness behind him and ricochet back when Hiei wasn't paying attention. Good thing it worked, too. Because if his shots didn't work that way, he had no other plans left.

"Two... one..." The last standing Hydra agent shows up with a hostage and goes into a standard Hydra rant about the organization's plans. He stops when he realizes that Cap is without his shield, Cap tells him that "It'll come if I whistle for it", the agent pulls a gun, Cap whistles... and his shield arcs down to hit the Hydra agent, leaving the hostage standing. That issue is full of him doing things like that; naturally, it's also the issue where it is lost.

- The Mighty Thor: Played with when Thor threatens to do this to Loki — he hurls away his hammer, then grabs Loki by the neck, and reminds him that NOTHING can prevent his hammer from returning to his hand. Oh, and would he be so kind as to remove the curse he placed before the hammer returns? Gee, look, it's starting to arc back already...

- Lensman: It's stated that this is likely to happen to Lensmen without the Sense of Perception who use energy weapons on the planet Trenco.

Perceivers are able to sense and correct for the distortion, knowing where the target really is and how not to shoot themselves.
- Buffy the Vampire Slayer. As a training exercise Giles blindfolds Buffy, hands her a ball, and asks her to throw it at him. She throws it in the wrong direction, he starts to wax sarcastic, and the ball bounces back and hits him in the head.

It's also exaggerated for comedy, since Percy lightly lobs the boomerang out the door and yet it returns with enough force to knock him down.
- Discussed in The Flash (2014), when Cisco is testing out Bette Sans Souci's superpowers (she can touch anything and turn it into an Action Bomb).

- One of your new tricks in Batman: Arkham City is to do this with Batarangs. The first example is in a hostage situation in a cutscene; following that, you can do it to thugs at will.

- The Legend of Zelda: Twilight Princess uses this as the way of defeating an early miniboss: he throws a boomerang from atop a set of columns, and if you roll into the column he's on after he's thrown the boomerang, destabilizing him, it'll knock him down when it returns.
- A very real problem in any Mario Kart game with the green shell. Miss your target and it's just as likely to come back and hit you.

- In Knights of the Old Coding, when Kuros finds the Axe of Agor, he discards the Knife of Throwing, forgetting that it always returns until it stabs him in the back.

- In The Mighty Thor's introductory episode of The Avengers: Earth's Mightiest Heroes!, "Thor the Mighty". Thor manages to hit three of the Wrecking Crew's four members by throwing his hammer. Then, he magically summons it to fly in the opposite direction, pummeling the fourth.

Thor: Then you should be familiar with attacking a foe from behind!
[Wrecker looks behind him and gets hit in the face with Mjölnir]

Redcoat: Ha! You missed!

- In the Duck Dodgers episode "Hooray for Hollywood Planet", Dodgers is attacked by a female assassin wielding energy nunchucks while all he has to defend himself is a banjo. After the instrument is cut in two, he throws the head part, but she just jumps above it and mocks him.
Nina: Ah! Did you think you could disarm me with a broken banjo?
Dodgers: That wasn't just any broken banjo. It was a Kookaburra Special Limited Resonance from Australia!

Upon seeing them going back towards him, Flash's response is a "DUH!"

- Double-Subverted in a cartoon: Wile E. buys "One Genuine Boomerang (Guaranteed to Return)" to use against the Road Runner, but when he hurls it, it seems to come and smack him from the other side of the screen (and change color from yellow to red before it is seen)... until the camera pans over to show the Road Runner standing next to a box for "Another Genuine Boomerang (Guaranteed to Return)". Wile E. starts to give chase... then his original boomerang comes back and hits him.
- In another cartoon, a boomerang Wile E. throws comes back with one of the dynamite darts he released earlier.
