Sometimes something is supposed to be so intuitive, the work needed from an actual person is minimal. This is rarely the case, but the thought of making something ridiculously easy is appealing.

This usually comes in two forms:
# An advertising slogan that touts the supposed intuitiveness of the product. Even accepting it as hyperbole, it's still rarely the case.
# Joking about how cliché or awesome an idea is so that a writer or director will supposedly know all they have to do just from that idea.

!!Examples of Variant 1:
* Spoofed in the 1948 movie ''Film/UnfaithfullyYours'' (but not the 1984 remake).
* Apple is fond of saying "Mac - it just works". For people who have never had any troubles with Windows [=PCs=], this is a reason Apple comes across as insulting and condescending.
** Or for people who have had troubles with Windows [=PCs=] but ''also'' with Macs. Of course, we all know the [[ real reason few people have trouble with Macs]] (other than the fact that few people have Macs).
** Ads for the new iPad make the claim that "You already know how to use it."
* The As-Seen-On-TV [=OneTouch=] Can Opener! This innovative invention, which is shown to "simply allow one to press the button and walk away, leaving a top that cannot pop a balloon", has some ''interesting'' side effects, which include: 1) not turning past halfway through the can, requiring one to spend time rewinding it back to the starting point; 2) not working unless at 100% battery power; and 3) (while indeed leaving a non-sharp top) making the can's edge so razor sharp that one is afraid to scoop anything out of it (also not allowing the food to be re-covered by the top).
* In 1976 Canon introduced the AE-1, the first 35mm camera with an embedded micro-computer; the commercial announced that Canon had "unmanned 35mm photography".
* Some [[TonkaTough Tonka]] commercials criticized other toys (like robots) for basically playing themselves, therefore not needing any human interaction, thus making them not fun. Unlike Tonkas of course.
* In the ''Series/DoctorWho'' episode "Partners in Crime", Adipose Industries markets their weight-loss "drug" with the slogan "[[ExactlyWhatItSaysOnTheTin the fat just walks away]]." And as even the Doctor had to admit, it ''was'' [[CutLexLuthorACheck a pretty effective weight-loss method]]...

!!Example of Variant 2:
* One sarcastic review of ''Film/SleepingDogsLie'' said, "I know! Let's write a movie where a guy practices cunnilingus on his cat! It practically writes itself!"
* In the episode of ''WesternAnimation/TheSimpsons'' where Homer is part of a barbershop quartet, he gets an idea for a song called "Baby on Board". Pretty much all the lyrics he comes up with are "something something", but he still says "this thing writes itself!" afterwards.
