Jimbob

Jimbob is a theoretical technician who ruins literally every technical task he attempts. Nobody can say for certain whether Jimbob truly exists, however it is asked of everyone to make accommodations for his incompetence. For example, if the correct technical solution to a problem involves buying a piece of gear that is moderately difficult to operate, then we can't buy that gear because Jimbob wouldn't know how to do that.

Like all technicians, Jimbob makes a convenient scapegoat, however unlike a competent technician, who can be blamed for things that don't go according to plan, Jimbob can be blamed for plans that don't go according to logic. Any time a logical solution would be expensive or inconvenient, it can be dismissed as "too complicated for Jimbob."

It is worth pointing out that Jimbob is distinct from They. Jimbob is the theoretical technican who is going to screw everything up, while They are the tech or techs who are to blame when everything has been screwed up.
