'''Trey Parker and Matt Stone''' are creative partners in crime, best known for being the creators of ''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 (Their first Hollywood Gig)
* ''Film/CannibalTheMusical''
* ''Film/{{Orgazmo}}''
* ''Franchise/SouthPark'':
** ''WesternAnimation/SouthPark''
** ''WesternAnimation/SouthParkBiggerLongerAndUncut''
** ''VideoGame/SouthParkTheStickOfTruth''
* ''Series/ThatsMyBush''
* ''Film/TeamAmericaWorldPolice''
* ''Theatre/TheBookOfMormon''
* They also record music for their various works backed by Bruce Howell, D. A. Young, and Nels Dielman under the rather vulgar name DVDA.

They also starred in ''Film/{{BASEketball}}'' ([[OldShame a fact that they are NOT proud of]]), but didn't write or direct.
!!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.
** Trey Parker is an admitted Japanophile, 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 Rob Schneider 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, left alone the characterizations. Celebrities will appear in a way that is grossly exaggerated and often has little to do with their public image.
* 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
* TheCastShowOff: Both of them are capable singers, as seen in ''WesternAnimation/SouthParkBiggerLongerAndUncut'' and ''Film/CannibalTheMusical''. Trey can speak fluent Japanese, and on occasion Matt and Trey will speak Spanish.
* {{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.
* CorruptChurch: Also a topic in their work, although they have attacked atheists and agnostics too.
* DerangedAnimation
* EqualOpportunityOffender: They themselves and plenty of others consider them to be this.
* HeyItsThatVoice: Will pretty much happen in any of their work, due to their tendency to do most of the voice work all by themselves.
* HereWeGoAgain: They lost the Academy Award for Best Song to PhilCollins at the 1999 Oscars, then had to go up against [[{{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".
* 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''.
* 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.
