- Sgt. "Topsy" Toppington (voiced by Stephen Root) — Toppington (nearly always referred to as "Topsy") is an old wartime buddy of Cotton Hill. He often acts as an accomplice to Cotton's inane hate- and revenge-driven schemes. He could inflate his cheeks in a manner similar to Dizzy Gillespie, and according to Cotton, he had to have all his teeth pulled out because they were badly decayed. In the episode, "When Cotton Comes Marching Home", Cotton reveals that during World War II, Topsy had strangled Hermann Goering. He also has not slept in fifty years, according to "Unfortunate Son." It is unknown whether this refers to a full night of sleep or sleep in general. In a later episode, he is left for dead after a failed scheme by Cotton who declares "He's playing checkers with the worms." In "Death Buys a Timeshare," his death is confirmed as Cotton is left his estate. Topsy was apparently flushed down General Patton's toilet, as his name can be seen along with all of Cotton's war buddies above the toilet.
- Stinkey (voiced by Edward Asner) — Stinkey is one of Cotton Hill's wartime friends who was overweight and had suffered from diabetes, he died at some point later in the series as it is mentioned by Cotton and his name is among the Veteran's ashes flushed down the toilet that General Patton used. Cotton spoke his name as he lay dying in the VA hospital.
- Irwin Linker (voiced by Jack Carter) — Irwin is one of Cotton Hill's wartime friends who is often seen with an oxygen tank. He was one of the few to not be named Stinky, Fatty, or Brooklyn. Peggy says he is a potty mouth. Irwin Linker was, like all of Cotton's war buddies, flushed down George S Patton's toilet.
- Ted "Pops" Popazito (voiced by Jim Cummings) — One of Cotton's war buddies who lived next to Bill for eighteen years. He often criticized Hank and his friends for using modern tools for housework. In "Movin' On Up," he died of a heart attack on his lawn mower and his house was rented by Luanne and some college friends. During the credits of the episode, Cotton and Topsy come to visit him only to be greeted by Griffin (one of Luanne's rude roommates) whom they attack for suspicion of murdering Pops and calling them Nazis.
