Terrance and Phillip

They are a comedic duo who live in Canada.

Apperance
Terrance (born Terrance Henry Stoot in the "small village" of Toronto) has black hair and wears a red shirt with a "T", while Phillip (Phillip Niles Argyle of Montréal) has blond hair and a blue shirt with a "P". Like virtually all Canadians in South Park, they are geometrically-figured with small beady eyes and Pac Man-like heads which flap up and down whenever they speak.

T.V. Show
In South Park, Terrance and Philip are the stars of a popular children's television show. This show-within-a-show serves an interesting role; the parents of the South Park characters view Terrance and Philip's obsessive fart gags in much the same way that many parents in the real world view South Park: with considerable contempt. The two characters have heavy accents, ostensibly to represent stereotypical American views of Canadians. (The "aboot" pronunciation has also been used in The Simpsons and Canadian Bacon. The fact their career is based on an accidental fart Phillip made on the The Ed Sullivan Show at the age of six, because that was the only part of their act Americans understood, may be saying something about Canadian perceptions of Americans.) The duo popularized a catchphrase in the show-within-a-show, as they would invariably say "You FAH-ted!" and then giggle to almost any farting sound. They are the favorite show of Stan, Kyle,  Cartman and,  Kenny

Popularity
Terrance and Phlip are huge celebrities within the South Park universe, and have won the Nobel Peace Prize. In one episode they briefly broke up, but then were reunited.

South Park: Bigger, Longer & Uncut
The Canadian comedic duo triggers a war between Canada and the United States with their foul-mouthed humor, especially the hit song "Uncle Fucka". The United States did not seek a UN resolution to invade Canadian territory, nor did it have a proper case of war citing self-defense. The Canadians were victims of American racial discrimination for which the United States did not even make a case of just war. The war was terminated when Satan and his consort Saddam Hussein made their appearance from Hell, awakening the two nations to their purposeless violence against each other. Unfortunately, the war was not stopped soon enough to save the Baldwin or Arquette families, who were a target of Canadian surgical strikes. In all, eight million people died in the conflict.
