->''"So, ten out of ten for style, but minus several million for good thinking."''
-->--'''Zaphod Beeblebrox''', from ''Literature/TheHitchhikersGuideToTheGalaxy'' by Creator/DouglasAdams

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-universe as being stupid or ridiculous, yet are treated as being [[MundaneMadeAwesome awesome]] or cool despite or because of this.'''

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.

[[AC:Live Action Television]]
* Many of the things Jeremy Clarkson builds on ''Series/TopGear''. Past examples have included a [[https://www.youtube.com/watch?v=vDlMLqdvHzI V8 powered blender]], a [[https://www.youtube.com/watch?v=COd5kAKac0U flamethrower mounted on a snowplough]], and [[https://www.youtube.com/watch?v=ggROOCxcZZI modding a car so much it caught fire]]. Although May and Hammond once converted a Reliant Robin (very small plastic three wheeled car) into [[https://www.youtube.com/watch?v=_b4WzWFKQ20 a space shuttle]] (which exploded on takeoff because it couldn't properly detach from the rockets, but details). 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 ''Series/HomeImprovement'', many of Tim Taylor's "improvements" on [[ShowWithinAShow Tool Time]]. One being a rocket-powered riding lawnmower.

* Music/TobyKeith said that he decided to record "[[https://www.youtube.com/watch?v=BKZqGJONH68 Red Solo Cup]]" because it was both the stupidest and most awesome song he had ever heard.

[[AC:Newspaper Comics]]
* ''ComicStrip/CalvinAndHobbes'''s [[TropeNamers trope naming]] [[http://assets.amuniversal.com/7669e540784d01302116001dd8b71c47 example:]] [[EverythingsBetterWithDinosaurs Tyrannosaurs]] [[AnachronismStew in F14's!]]
--> '''Calvin:''' "This is '''so''' cool!"\\
'''Hobbes:''' "This is '''so''' stupid."

[[AC:Tabletop Games]]
* 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.
* ''TabletopGame/{{GURPS}}'' Ultra-Tech has the rocket striker. It's a swinging melee weapon ''with a rocket engine attached for extra power''. Yes, you read that right. May be either SoBadItsGood or just far too silly for the setting.
* ''TabletopGame/{{Rifts}}'' has no such compunctious, however, and will gladly introduce weapons like the bangstick, a truncheon (also available in staff and hammer) with a single-round shotgun chamber built into one end and an impact trigger. It sells like hotcakes because Rifts' Earth adventurers and mercenaries are stated in-universe to live and die by RuleOfCool, and many of them love the concept of being able to finish off the enemy by [[CherryTapping poking them with a stick]].
** The funny part is, something basically similar ''[[http://en.wikipedia.org/wiki/Powerhead really exists]]'' and is [[NotCompletelyUseless perfectly practical but highly situational.]]

[[AC:Video Games]]
* The Civilopedia, the in-game encyclopedia of the ''VideoGame/{{Civilization}}'' series, has this opinion (quite vocally) about HumongousMecha. In Civ 5, it admits flat-out that mecha are [[AwesomeButImpractical deadly, but completely inefficient]], far too vulnerable to the enemy, [[MundaneSolution and could be outdone by]] [[TankGoodness chopping off the legs and putting the rest of it on treads]]. But they're ''[[RuleOfCool just too cool]]'' to not have.

[[AC:Web Animation]]
* [[WebAnimation/{{PonyDotMov}} SWAG.MOV]]'s climactic battle [[spoiler:between a {{Kaiju}}-sized Rainbow Dash and Discord]]. The FreezeFrameBonus in this scene reads, "THIS IS SO FUCKING RETARDED OH MY GOD I CAN'T BELIEVE I'M ANIMATING THIS".

* 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 ''Franchise/{{Ghostbusters}}'' theme) reads, "Very stupid ideas taken very seriously. Dr. [=McNinja=]."
* Sword-chucks[[note]]That's nunchucks made out of swords. They're even stupider than they sound.[[/note]] 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.
* In ''Webcomic/KnightsOfBuenaVista'', this is how Mary feels about watching a Creator/MichaelBay movie.
-->"I ''know'' his movies are really stupid. That's ''WHY'' I like them."

[[AC: Web Video]]
* In ''WebVideo/AtopTheFourthWall'''s review of ''ComicBook/BruteForce'', Linkara acknowledges this about the comic.
* ''WebVideo/HonestTrailers'': This is the Narrator's opinion of ''Film/PacificRim''. He dubs it "either ''The Most Awesome Dumb Movie Ever Made'' or ''The Dumbest Awesome Movie Ever Made''."
-->'''Narrator''': Let's be honest, that movie was super dumb. But I still cannot wait for the sequel!
* Brand in ''WebVideo/MidnightScreenings'' felt that ''Film/TransformersAgeOfExtinction'' worked better than the other films due to being just stupid enough to avoid pissing him off, and having the cool aspects that he enjoyed in other Creator/MichaelBay films.

[[AC:Western Animation]]
* The martians of ''WesternAnimation/InvaderZim'' destroyed their own civilization and worked themselves to extinction to turn Mars into a workable space-craft (except, of course, that upon completion there was no-one left to drive it). Why? ''Because it was cool.''
