 Comedy Central originally ordered only six episodes of South Park for the first season 's initial run . However , when the show proved to be a success , they requested an additional seven , the first ones of which creators Trey Parker and Matt Stone had to produce quickly . " Pinkeye " was the first of those new seven episodes to be produced . It was also the first South Park Halloween episode . The script was written by Parker , Stone and writer Philip Stark , and was directed by Parker and Stone , who made the pinkeye a major element of the plot because they associate the illness with the elementary school experience . Parker said , " Pinkeye is just such a huge part of your life when you 're in third grade . Pinkeye is the thing every third grader gets and it 's just such a bizarre thing . " In writing the episode , Parker said he wanted to convey his belief that Halloween is a positive holiday , especially for children : " Halloween 's a great thing . That was part of what we wanted ( to say ) . I think kids having this kind of mythology is great . "
