Farmer Carl Denkins is a farmer who lives just outside of South Park.
He made many further brief appearances - some of his chickens were molested by the chickenlover in "Chickenlover", and in "Scott Tenorman Must Die", Cartman tricked him into believing that Mr. and Mrs. Tenorman, Scott Tenorman's parents, were trespassing pony killers, and he then shot and killed both of them. He also appeared in the episode "Fun with Veal", although he was referred to as "Rancher Bob" in this appearance, implying that his middle name may be Robert.
His final major appearance was as one of the pro-war "rednecks" in "I'm a Little Bit Country", though he has made at least one minor appearance since. He also returns in a similar role in "White People Renovating Houses" being part of the group of protesting rednecks.
He wears a red jacket with blue buttons and two side pockets, a brown belt with a silver-colored buckle, blue jeans, black boots, and a black cowboy hat with a white band. He has brown hair with sideburns, thick eyebrows, and a thick mustache.
