The intersection of the sets "Stupid things" and "Awesome things", which, surprisingly, are non-disjoint sets. A field mainly occupied by the obsessions of 8-year old boys, but one that can be surprisingly fertile for all that.

'''Examples should be confined to things that are acknowledged in-show as being stupid or ridiculous, yet are treated as being [[MundaneMadeAwesome awesome]] or cool anyway or because of.'''

Differs from SoBadItsGood and SoCoolItsAwesome by being the localized case; those apply to the whole show. See also AchievementsInIgnorance, a SisterTrope: when the "impossible" is achieved due to not knowing it's impossible; frequently, cases of CoolButStupid are acknowledged as being stupid, but carry on regardless "just to see what will happen". Compare AwesomeButImpractical.

!!Examples

* ''CalvinAndHobbes'''s trope naming example: [[EverythingsBetterWithDinosaurs Tyrannosaurs]] [[AnachronismStew in F14's!]]
--> '''Calvin:''' "This is '''so''' cool!"\\
'''Hobbes:''' "This is '''so''' stupid."
* The AltText for [[http://drmcninja.com/archives/comic/20p67 this]] strip of ''Webcomic/TheAdventuresOfDrMcNinja'' (in which Doc focuses his energy to fight ghosts by humming the ''Film/{{Ghostbusters}}'' theme) reads, "Very stupid ideas taken very seriously. Dr. [=McNinja=]."
* Flavor text from ''TabletopGame/DungeonsAndDragons'' suggests that most of the [[OurGnomesAreWeirder gnomes']] most brilliant inventions started with astoundingly dumb ideas. For instance, the Gnomish Magnetic Armor, which [[AntiMagic repels magical attacks]], was originally intended to repel metal debris on workroom floors.
* Many of the things Jeremy Clarkson builds on ''TopGear''. Past examples have included a V8 powered blender, a flamethrower mounted on a snowplough, and modding a car so much it caught fire. Although May and Hammond once converted a Reliant Robin (very small plastic three wheeled car) into a space shuttle. It is also their opinion of the [[http://en.wikipedia.org/wiki/Pagani_Zonda Pagani Zonda]]. The ''TopGear'' equivalent of CoolButStupid, frequently leveled as a judgment on their own projects, is "Ambitious but rubbish."
* Many a "carry the myth to its logical conclusion" test on ''Series/MythBusters''. Past examples include a car with dimples like a golf ball and a boat made out of duct tape.
--> '''Adam:''' I've just had one of those "what the hell are we doing" moments.
* In ''WebVideo/AtopTheFourthWall'''s review of ''ComicBook/BruteForce'', Linkara acknowledges this about the comic.
* Kamina from ''GurrenLagann'' could be considered this as applied to characters rather than ideas. If there's anything to prove that being an IdiotHero does not prevent you from being a RatedMForManly MemeticBadass, it's him.
* Sword-chucks[[hottip:*:That's nunchucks made out of swords. They're even stupider than they sound.]] in ''[[Webcomic/EightBitTheater 8-Bit Theater]]''. Every character except their inventor is fully aware of how completely idiotic this is, but they end up working perfectly.
** In a guest comic, Fighter even makes staff-chucks to cast spells with. They're considered even more ridiculous and turn out to spray destructive magic uncontrollably when used. Since he made them as a gift for [[HeroicComedicSociopath Black Mage]], it all works out.
* TobyKeith said that he decided to record "Red Solo Cup" because it was both the stupidest and most awesome song he had ever heard.
