a cog ON the wheelI noticed in the Bankruptcy reveal stream, he said that his old office jahb treated him as "a cog in the wheel", when the expression is "a cog in the machine".
a cog on the GEAR
honestly sounds more like being part of a cohesive, efficient team
wheel doesn't have the cold negative connotations that machine has
he probably lifted wheel from "crushed under the wheel" or "grinding wheel"
at this point i don't know if he's accidentally mashing phrases, or he's putting them together on purpose to sound smarter
