[[/folder]]

This is often done by doctors or friends of the patient who genuinely mean well, and are just trying to help them. However, it can also be used as a sarcastic [[PreMortemOneLiner Pre-Mortem]]/PreAsskickingOneLiner by someone who is about to inflict a lot of ''deliberate'' pain on their victim. Or to imply they'll die too quickly to feel anything.

* Lampshaded (then averted) in ''Film/{{Deadpool}}''. [[MadScientist Ajax]] tells Wade Wilson that he ''could'' speak in euphemisms ("This may hurt", "take a deep breath", etc.), but since he's completely insensitive (both [[TheSociopath emotionally]] and [[FeelNoPain physically]]) he doesn't really give a crap, so he just says what he'll actually do: torture Wade mercilessly until his mutant gene activates. Then he proceeds to do exactly that.

* Beautifully averted in ''Film/{{Hook}}'', where Hook is about to pierce Peter's son's ear and tells him 'Brace yourself lad, because this is REALLY going to hurt.'

* Towards the end of ''VideoGame/TheLegendOfHeroesTrailsOfColdSteel'', [[spoiler:Sharon Krueger, the Severing Chains]] subverts this. She shows up to help the instructors of Thors [[spoiler:fight the Soldats units.]] She says that that she'd say "You won't feel a thing," but admits point-blank that do so would be an untruth.

* In Telltale's ''VideoGame/TheWalkingDead'' season 2, at one point Clementine has to [[spoiler:help disinfect Kenny's eye, which was severely injured in a previous episode]]. You are given the choice to either say the trope name, or be more honest about how painful the procedure is going to be. Or, [[VideoGameCrueltyPotential if you're feeling extra dickish]], [[InvertedTrope make it sound like it's going to be extra painful]].

* ''WesternAnimation/CourageTheCowardlyDog'': Dr. Vindaloo describes the implantation of a Kangaroo Monster's bone as a "very delicate procedure" which is really just hammering the bone into Eustace's back (and later Courage).
