* ''VideoGame/{{Portal 2}}'': During the final levels most locations need repulsion gel, propulsion gel or conversion gel, which is usually pouring out of a broken pipe. So during the boss fight, all pipes are sealed, leaving you without gel or even portals. As you can no longer use portals, [[spoiler:Wheatley]] happily throws bombs at you, knowing you can't send them back like you did in the first game. Thing is, the bombs are more than capable of breaking those pipes, spreading conversion gel which lets you place the portals needed to throw back the bombs. [[spoiler: This is [[JustifiedTrope understandable]], given [[IdiotBall who Wheatley is]]]]. The bombs were also wholly redundant based on the immediate flow of neurotoxin. More patience would have meant a win anyway.

* One of Creator/GKChesterton's ''[[http://gutenberg.net.au/ebooks05/0500421.txt Paradoxes of Mr Pond]]'', "The Three Horsemen of the Apocalypse," concerns a field marshal whose soldiers were ''too'' eager to obey his orders. The marshal sent the first of the three horsemen with orders to execute a politically troublesome poet; when the prince arrived, fully aware of the marshal's intentions, he sent a second horseman to carry a reprieve. The marshal then sent a third horseman with orders to shoot the second; unfortunately, the first horseman surmised the second horseman's purpose and shot him, so the third horseman ended up shooting the first horseman by mistake. As a result, the execution order never reached its destination, and the poet went free, much to the marshal's consternation.

* An unintentional example in ''Comicbook/TintinInAmerica''. A gangster tries to throw a vase at Tintin from behind to knock him out. However as he throws the vase Al Capone opens the door Tintin is listening at, knocking his gun away unintentionally, but causing him to be hit by the vase and knocked out. This allows Tintin to incapacitate Pietro and evade the other gangster.

ReverseThePolarity, a PoisonedChaliceSwitcheroo, and LotsaPeopleTryToDunIt can all easily lead to this.

* If you befriended Papyrus in ''VideoGame/{{Undertale}}'', then you'll recieve a call from him in Waterfall asking what you're wearing. As it turns out, he's asking on behalf of Undyne, who is trying to hunt you down and kill you. Should you lie to him, or tell the truth but change up your equipment later, then Papyrus will tell her that you were wearing something else in an effort to cover for you... [[AccidentalTruth not realising that he'd described the exact thing you were actually wearing.]][[note]]If you don't do either of these things then [[SchrodingersGun he'll opt to tell her the truth instead]], assuming that you'd realised something was up and given him a false answer. [[MortonsFork Either way, Undyne ends up coming after you]].[[/note]]
