We had an IT guy like that. Totally inept at his job, but wow, could he tell some tall tales! My response was a disgusted look and a dry, "Yeah, sure you did, Bill." Among his claims- he once helped Barbara Bush sneak out of the Bush Presidential Library, right under the noses of the Secret Service, and brought her back to his place where they got totally smashed on margaritas; the FBI (or was it CIA? Maybe both!) brought him a laptop to crack, because they couldn't do it - and this guy couldn't even master Outlook; and when he was a bull rider, he would smoke a cigarette almost to the filter and drop it into the animal's ear just before the chute opened, to get a better ride (I can just about guarantee that if PRCA or PBR didn't break him with fines and pull his sanction permanently, PETA would rip him to shreds- or what was left of him after his fellow riders got done with him!).
Foul, useless, creepy little man, but he did have some entertainment value, at least.
