He does, and falls off, waking up as his "normal" self and being confused as to why he's holding a rattle.

** Played with. In one episode, Squidward gets hit in the face by a door, and the resulting alteration to his bone structure causes him to become ridiculously handsome, so much as to attract copious amounts of attention from both [[EvenTheGuysWantHim men and women.]] After becoming overwhelmed with his newfound status, he attempts to become normal again, getting hit in the face with the same door several times again. This just makes him even ''more'' beautiful, however, only going back to normal after getting hit in the face with a pole after running to avoid a falling [[BrickJoke shoe]].

* On one ''WesternAnimation/TomAndJerry'' cartoon, Tom gets a TapOnTheHead and thinks he's a mouse. Jerry tries to get Tom hit again to return him to normal and eventually succeeds. Unfortunately, Mammy has the same idea, and Tom is back as a mouse for the IrisOut.

* ''ComicBook/{{Asterix}}'': In ''Recap/AsterixAndTheBigFight'', Getafix loses his memory when Obelix inadvertently strikes him with a menhir.

* In ''Anime/OddTaxi'', it's revealed in the last episode that Odokowa's unusual condition is the result of a [[spoiler:brain injury from his childhood when his mother attempted murder-suicide by driving the family car into the ocean.

** The above is expanded on in the episode "Believe It or Not, Joe's Walkin' on Air" where Joe gets leg replacement surgery that allows him to walk again. This also turns him into a jerk who ditches his old friends for new athletic ones, and then he even leaves his wife. His friends, wanting the old Joe back, try to re-cripple him, but are no match for him athletically. His wife, also wanting her husband back, then shoots him to try to recripple him, but keeps missing his spine. Joe, in pain, tells her to give him the gun and shoots himself in the spine, making him a paraplegic again and [[ResetButton everything goes back to the way it was.]]

This is especially popular with EasyAmnesia, where an accidental [[TapOnTheHead bonk on the head]] in the beginning of an episode will be reversed by an accidental (or intentional) bonk on the head later.

* Subverted in the 2004 short film, ''Fluent Dysphasia''. A guy gets hit on the head, and wakes up speaking fluent Gaelic, and can no longer understand English.
