The problem with these stories, and pretty much any that use shock as there source of humor, is that they just aren't that funny. "It's just a joke" only works if the content actually develops a punchline. But instead, it's the same story, over and over again. The only change is that the BOFH goes from fighting with incompetent vendors foisted on him by management to just being the same, exact kind of dick to the people he's supposed to be supporting, making him exactly the same, frustratingly useless "help" he complains about with the vendors.

Even with a reading that these are projections of what he sees as how other people see him (he doesn't actually want to watch cartoons all day and delete peoples files intentionally, that's just what people think he does), the joke runs tired after the 3rd iteration, and then continues ad nauseum.
