John Peters--you know, the farmer, is one of Night Vale's most well-known agriculturalists and a frequent call-in contributor to Welcome to Night Vale. He owns a peach orchard which has never yielded any peaches. His specialty crop is imaginary corn (and Oranges as seen in episode Orange Grove for a time), for which he receives an annual subsidy of $500,000. He seems to have some connection to The House That Doesn't Exist. The connection is currently not known.
The suffix "You know, the farmer" seems to be required when speaking of him, and nobody is really sure why. There is no evidence to why the suffix is in place, but a few times in Orange Grove, Cecil just calls him John Peters. Steve Carlsberg also uses the suffix, but Cecil replies, "Yes, I know" in a serious and slightly overdramatic tone as a wink to the audience as to allude to the comedic aspect of his acquired "title".John Peters - you know, the farmer - is voiced by Mark Gagliardi - you know, the actor - known for Drunk History and The Thrilling Adventure Hour.
