Simpleminded Wisdom

A "simple" character (particularly a servant or rural character) displays uncommon wisdom -- usually much to the surprise of an arrogant main character. Creates An Aesop moment.

This would seem to derive from Cervantes' Don Quixote, where the archetypically "simple" Sancho Panza occasionally produces statements of great wisdom (although in that case the main character, Don Quixote, often fails to notice or credit that wisdom).

Compare Dumbass Has a Point, which is what said Insufferable Genius may say after hearing the simple character's idea.

Comics

 * Not a perfect example, but the Rhino in Spider Man does this occasionally, much to the surprise of other villains.
 * In Twisted Toyfare Theatre, Mego Spider-Man seems to totally lack his signature super-powers, but also happens to be the only person in Megoville apart from maybe Dr. Doom who has a single lick of common sense.

Literature

 * The Scarecrow from The Wonderful Wizard of Oz, both the book and movie. He wishes for a brain, yet neither he nor anyone else he's traveling with notices the discrepancy.
 * Older Than Steam: The Beast in the original literary fairy tale Beauty and The Beast is described as speaking with much common sense, but "never what the world calls wit." (And yes, at the end of the story, the Prince is transformed to be witty and eloquent in addition to handsome.)
 * In Alexander Pope's The Rape of the Lock, right before the incredibly epic battle over an involuntary haircut, Clarissa, probably a lower-status lady than most of the players, rebukes everyone on how it's silly to waste energy over such a trivial matter, and how good humor is a better tool than beauty or tantrums to weather the storms of life. Of course, no one listens to her.

Live Action Television

 * Sheriff Carter, from Eureka.
 * Jack O'Neill of Stargate SG 1 often falls into this.

Web Comics

 * In The Inexplicable Adventures of Bob, this is very nearly Bob's most prominent personality trait.

Western Animation
"Pinkie Pie: (holding a book) The Elements of Harmony: A Reference Guide
 * Patrick Star from Spongebob SquarePants.
 * Pinky, from Pinky and The Brain, on those rare times when he is pondering what Brain is pondering.
 * While usually the Cloudcuckoolander, Pinkie Pie sometimes has shades of this in My Little Pony Friendship Is Magic.
 * When Twilight can't find any information in her library about the Elements of Harmony:

Twilight: How did you find that?

Pinkie Pie: (singsong) It was under E!"


 * Stan Marsh from South Park, although he's not an idiot like most examples.
