The Old Farmer is an older man who occasionally advises South Park citizens on their problems, though is rarely involved in them himself. He is based on the character Jud Crandall from the film Pet Sematary.
He first appeared when Butters passed by his shop while lost in "Butters' Very Own Episode". Butters asked him which road to take to go back to South Park. The Old Farmer then pointed to a cursed road, and began describing its horrible history, reciting a quote from the book, "A lot of history on that road". The cursed road also appears in Pet Sematary.
He reappeared in "Asspen" where he warned Stan about how dangerous skiing the K-13 would be, saying there was a 'wolf boy' who escaped from a mental institution up there as well as the mountain being a burial ground cursed by vampire cannibalistic Indians named the 'Witchicaw' who ate the flesh of little children.
His third appearance was in "Marjorine". After Butters faked his death, the farmer comes to his parents' house, telling Stephen Stotch not to try to bring his son back by burying his body in the Indian Burial Ground, quoting "Sometimes dead is better". Unfortunately, he is the one who gives Stephen the idea.
He reappears again in "Insecurity" at the bar when the fathers try to decide how to deal with the UPS man who is supposedly sleeping with their wives. The farmer compares the UPS man to a milk man he once knew and tells them they should kill him, and insists it's the only way. Later, he makes the same comparison to the security system people.
He later appears in "The Damned", running a farm. When Randy Marsh talks to him to learn more about the Member Berries, the farmer tells him how popular the member berries are and how he had to remove several of his other crops to make room for them.
He again returns in "Tegridy Farms Halloween Special" as a worker at the Natural History Museum, warning Butters to not put the Mummy Stamp into his book.
He seems to be caring, to some extent, warning Butters of the dangers of going down a certain road in "Butters' Very Own Episode", as well as warning Stephen Stotch of the dangers of burying his son in the Indian Burial Ground in "Marjorine". However, the advice he gives almost always scares the person he is talking to more than it comforts them. Usually discussing monsters, or other horrific supernatural occurrences in the place he's talking about. His advice also always causes more problems than it could possibly solve, such as advising men concerned about the UPS man sleeping with their wives to commit murder, or warning Stephen Stotch about the horrific consequences of reviving his son in an ancient Indian Burial Ground when Stotch didn't even know that the graveyard existed, making it possible for him to revive Butters.
The Old Farmer has gray hair, thick eyebrows and has many wrinkles on his face, his eyes appear to be smaller than most adult characters, he also has a very wide mouth. He originally wore a dark blue shirt with rolled up sleeves underneath a lighter blue overall. His overall had two pockets, one to the left and one to the right, there were also two black stains on the overall. Underneath his overall he wore a white undershirt. He also wore black shoes and a yellow hat.From Insecurity onwards, he was redesigned. His hat and shoes are now more detailed, as are his face and hair. He no longer wears a visible white undershirt and his overall now also has more details. The two pockets are now one central pocket and there are no longer stains to be found. He is shown to be taller than other adults in previous seasons.
