The Business Men become a problem when they build a giant Finn robot and begin capturing Fuzzy Friends, claiming they are "protecting them." Finn fires the Business Men for this, which causes them to lose control. Finn decides to "take them down," necessitating fat, lazy Jake's reentry into the conflict. The Business Men suck enormous Jake up into the tube leading to the "care sac" attached to robo-Finn. The contraption explodes, launching all of them into the air; Finn re-hires the men as they free fall, but the job for which he hires them is to go back into their iceberg.
Pendleton Ward stated that the Land of Ooo is a post-apocalyptic world, and that the Business Men might be left behind from the 21st century. Although they create the conflict of the episode, they are not villainous in the traditional sense. The Business Men appear to only understand work as we know it in contemporary 21st century America, and everything else is structured around the efficient implementation of that employment. They seem to have some shadow of creativity and internal motivation, but only within the construct of a hierarchical business (in which Finn and Jake are the bosses, not them). Their loss of identity without their job, and that they remember nothing of their humanity but their careers, could read as social commentary on the nature of modern full-time work and its zombie-like effect on the psyche (e.g., "working stiff"). The individual names of the Business Men are not specified.
The Business Men resemble stereotypical zombies by their discolored skin (tinted blue) and their numerous boils. Due to their tenuous grasp of English, they appear somewhat simple; however, their ability to effectively deal with situations show that they may retain some degree of intelligence. Jake describes them as "well-dressed pickles."
Their leader (voiced by Brian Posehn) wears a red necktie and has black hair, while the others have blue ties and brown hair.
Business Men's machine
The Business Men's Machine is a large robotic device used to capture the Fuzzy Friends in order to better protect them. The machine resembles a robotic version of Finn, except with three legs and a vacuum device used to capture things. The machine was destroyed when Jake rapidly expanded his body while partially inside it, causing it to explode.
- The Business Men seem to exhibit a trend of the monsters based on classic supernatural threats in this world wearing business suits (with them being tied to zombies); this includes the Why-wolves, who are connected to werewolves, and Hunson Abadeer, who is a demon.
- Finn doesn't react to them as other humans like he did in "Susan Strong."
- Adam Muto nicknamed them "The Bills." 
- When fighting the Battle Cubes, the Business Men use different armor and weapons from different time periods: a knight's flail, a samurai's katana, a Spartan shield and spear, as well as Jake's axe.
- It is unknown if they are still considered "human," or since they have been frozen for so long that their humanity has been exhausted and are considered a new species.
- They seem to have a large knowledge about technology, making and programming satellite observation systems and robots.
- In the episode "Candy Streets," Jake stretches into a lawyer that resembles the Business Men.
