Trey Parker (born Randolph Severn Parker III, October 19, 1969) and Matt Stone (born Matthew Richard Stone, May 26, 1971) are creative partners in crime, best known for being the creators of Creator/ComedyCentral's [[LongRunner long-running]], brutally satirical, extremely vulgar animated sitcom ''WesternAnimation/SouthPark''. The two became friends in college and made their first short, ''The Spirit of Christmas'' (aka ''Jesus vs. Frosty''), that caught the eye of many and got ''WesternAnimation/SouthPark'' launched as the success it [[LongRunners still is.]]

!!Creative works by the two include:
* ''Your Studio and You'' [[/index]](Their first Hollywood gig, an internal video for Creator/{{Universal}} after their buyout by the liquor company Seagram in the mid 90s; [[{{Homage}} modeled after a 50s educational short]], filled with famous cameos)
* ''Time Warped'' (two pilots- one for Creator/{{Fox}}, the other for Creator/FoxKids- intended as a "musical romp through time")
* ''Film/CannibalTheMusical''
* ''Film/{{Orgazmo}}''
* ''Franchise/SouthPark'':
** ''WesternAnimation/SouthPark''
** ''WesternAnimation/SouthParkBiggerLongerAndUncut''
** ''VideoGame/SouthParkTheStickOfTruth''
** ''VideoGame/SouthParkTheFracturedButWhole''
* ''Series/ThatsMyBush'', a live-action Comedy Central sitcom about George W. Bush's first year in office
* ''Film/TeamAmericaWorldPolice''
* ''Theatre/TheBookOfMormon''
* ''Princess''[[note]] A very explicit web cartoon that lasted two episodes around the life of a dog [[/note]]
* They also record music for their various works backed by Bruce Howell, D. A. Young, and Nels Dielman under the rather vulgar name DVDA[[note]]stands for "double vaginal, double anal" and is mostly seen in hardcore porn movies[[/note]].

They also starred in ''Film/{{BASEketball}}'' ([[OldShame a fact that they are NOT proud of]]), but didn't write or direct. Trey has also voiced the villain in ''WesternAnimation/DespicableMe3'', [[PlayingAgainstType a very different turn from the duo's]] [[SoMyKidsCanWatch usual adult fare]].
!!Tropes related to the creators:
* AmusingInjuries: A staple in their work.
* AuthorAppeal:
** They like reasons to include Mormonism in their works. This includes a Mormon missionary as the main character in ''Orgazmo'', a ''WesternAnimation/SouthPark'' episode ("All About Mormons") dedicated to the religion, and ''Theatre/TheBookOfMormon''.
** They enjoy throwing in musical numbers into their works, due to their love of musical theater (similar to Creator/SethMacFarlane doing the same on his three animated sitcoms).
** Trey Parker is an admitted Japanophile and actually knows the language, so you can pretty much expect any use of the Japanese language in their work to be some kind of BilingualBonus.
** They also have a soft spot for imbecilic voices and laughable speech impediments.
** Being big fans of LiveAction/MontyPythonsFlyingCircus they have referenced the show and its style often in their work.
* AuthorCatchphrase: "Derp" was apparently a nonsense word invented on the set of ''[=BASEketball=]'' to exemplify stupid humor. It has been carried over to WesternAnimation/SouthPark in several forms, with no in-show explanation or link between them. Once there was a substitute school chef named "Mr. Derp" who did stupid physical gags; another time there was a Creator/RobSchneider movie trailer (as part of a running gag of successively stupider movie trailers) whose narration consisted almost entirely of nonsensical permutations of the word "Derp". The movie title is ''Da Derp Dee Derp Da Teetley Derpee Derpee Dumb''.
** "[[RunningGag Rated PG-13]]."
* BadImpressionists: They deliberately put no effort in their celebrity voice impersonations, let alone the characterizations. Celebrities will appear in a way that is grossly exaggerated and often has little to do with their public image.
* BerserkButton: Barbra Streisand once insulted the duo's home state of Colorado in an interview. They responded by depicting her as a robot destroying South Park in "Mecha-Streisand", and even her very name is a swear word in of itself in BLU. Bottom line: don't mess with Colorado!
** They also do ''not'' like hearing their show compared with ''WesternAnimation/FamilyGuy''.
* BigEater: In the behind-the-scenes ''WesternAnimation/SouthPark'' documentary, Parker reveals that, when writing, he eats copious amounts of [=McDonald's=] food... [[AndADietCoke and a Coke Zero]].
* BlackComedy: Their staple.
* CorruptChurch: Also a topic in their work, although they have attacked atheists and agnostics too.
* DerangedAnimation
* EqualOpportunityOffender: Their personal philosophy has always been "If one thing is off limits, then everything is."
* {{Garfunkel}}: Parker is the chief creative force behind the duo, with Stone playing more of a supportive role. Stone seems to have made peace with his secondary role in group judging by his answers to interviewers. For his part, Parker says that he considers their work relationship to be a partnership and that their joint ventures would not be the same without Stone's input. He also says that Stone has a more forceful personality and will take charge in situations where Parker is more likely to bend to pressure.
* HereWeGoAgain: They lost the Academy Award for Best Song to Music/PhilCollins at the 1999 Oscars (Collins won it for his songs in Creator/{{Disney}} Animation's newest [[Franchise/DisneyAnimatedCanon animated classic]], ''Disney/{{Tarzan}}''), then had to go up against [[Music/{{U2}} Bono and The Edge]] in the 65th Tony Awards, with Trey especially despising the idea of losing to both Phil Collins and Bono in one lifetime. They didn't, and won '''nine''' Tonies.
* HeterosexualLifePartners: The two have been friends since college. Stan and Kyle's relationship in ''WesternAnimation/SouthPark'' makes this trope evident even more, considering the two are based on their creators (Stan being Trey and Kyle being Matt).
* ManOfAThousandVoices: South Park features the voices of the two for every male character with very few, case-by-case exceptions. And they flat out admit their imitations of celebrities are done "poorly".
* NotSoAboveItAll: They HAVE actually been involved in celebrity causes (notably the WM3 case involving three teenagers falsely convicted of murder); though in fairness it later turned out that the kids WERE innocent.
* RunningGag: Back in the early seasons when they introduced each episode of ''South Park'' at the beginning, they would refer to each episode as their favorite episode.
* RefugeInAudacity: They are [[WordOfGod "Equal opportunity offenders"]] after all.
* SelfPlagiarism: Trey & Matt wrote the gag song "Montage" for an episode of ''WesternAnimation/SouthPark'', but the same song was used in their completely unrelated movie ''Film/TeamAmericaWorldPolice''.
* StageNames: While Stone uses a shortened version of given name Matthew, Parker's name is actually Randolph Severn Parker III - and given "Three" is [[BilingualBonus "Tre" in Italian...]]
* TechnicianVersusPerformer: Parker is clearly the more creative of the two, while Stone handles more of the business side (fitting, as his father was an economist). See "{{Garfunkel}}".
* TerribleArtist: Parker and Stone enjoy StylisticSuck. They deliberately don't make the animation in ''South Park'' and ''Team America'' too good, because they enjoy the jerky movements.
** Subverted with ''Theatre/TheBookOfMormon'', which looks just as professional as any other broadway musical.
* ThrowTheDogABone: In recent years, they've been treating their designated ButtMonkey Butters with much more dignity. For instance, when Butters does finally break and attempts suicide, it's not played for laughs and his injuries stay with him for the rest of the season.
