I once butted heads with a buffoon who was basically a manifestation of a Will Ferrell manchild character, right down to looking exactly like Will Ferrell. He claimed to know IT stuff; he did not, but had convinced the COO that he did. I contradicted him on something, on the record, which a year later I was proven right about so he left me alone.
But, got to watch him get a [nonbinary] coworker that I liked quite a lot fired before they rumbled exactly how badly they had been played.
