"You Said You Would Let Them Go!" moments in Comic Books.
- Buffy the Vampire Slayer: The heroine does this to a captured vampire in the Wolves at the Gates Arc of season eight.
- Darth Vader: Dark Lord of the Sith. Darth Vader captures a family of bounty hunters who tried to kill him and threatens to kill their daughter unless they reveal who hired them. They're smart enough to insist that he let her go first, and make her swear that she won't seek revenge for their inevitable deaths so that Vader won't regard her as a threat he has to hunt down and kill. She's a younger Chanath Cha, the bounty hunter from Star Wars: Lando, so this is one deal he apparently decided to keep.
- Disney Ducks Comic Universe: In one Carl Barks comic, Magica DeSpell turns Donald Duck and his nephews into animals (well... non-anthropomorphic animals...) and says that she'll only turn them back if Scrooge gives her his dime. Naturally, she doesn't.
- The Joker does this constantly. Then again who would really trust the Joker in the first place?
- Happens in Judge Dredd, when a man helps the other three Dark Judges (y'know, the ones dedicated to extinguishing all life?) free Judge Death on the condition they don't kill his wife. Naturally, "WE LIED!"
- MAD's parody of The Godfather Part II has Michael promise his sister that he'll never kill their brother Fredo, despite Fredo's treachery, while their mother is alive. Then he tells his consigliere to "put out a contract on Mom." Well, he didn't lie.
- The Transformers (Marvel): Invoked and inverted in an early issue where Ratchet does a deal with Megatron whereby Ratchet will help Megatron takes back control of the Decepticons from Shockwave in return for him surrendering control of the Ark, where most of the other Autobots lie deactivated. In the end, Ratchet (falsely) tells Megatron he's fulfilled his side of the bargain, Megatron reveals he has no intention of fulfilling his and Ratchet reveals he's already prepared for that and has the Dinobots waiting in ambush.
- From Usagi Yojimbo:Tomoe: "You promised you would release Usagi if I turned myself over to you, Noriko!"
Noriko: "Don't be an idiot."
