It's impossible to avoid know-it-all idiots like that in the work place. Every few years we get one like that and they don't last long.
Most memorable guy we had was named Andre. He knew everything about any and all subjects. He constantly bragged about his dad who was a "millionaire 5 times over" and yet Andre lived in a run down hillbilly shack in Gary Indiana.
The dude never shut up, at the end of the day you could hear his voice echoing in your head. If you knew you'd be working with him the next day, you made damn sure to bring some extra strength Tylenol along.
He'd see a Ferrari go by and instantly claim his aunt has one just like it. He also claimed to be a martial arts expert that TRAINED WITH CHUCK NORRIS and could clear out an entire bar within minutes. His obsession was knowing famous stars from the 70's...he claimed to personally know the bionic man, the bionic womam and the guy from Hart to Hart. His aunt was a famous cook for these people and he often ate dinner with them when he lived with his millionaire dad in California.
If you even hinted at calling his bluff on something he'd start to get pissed. He was actually going to smash a cinder block once with his head to prove his martial arts expertise but one of our guys stopped him before he knocked himself out.
At first he was our entertainment but it got old and everyone was fighting over who would get stuck taking him for the day.
Service manager gave him to the shop as a Christmas present from hell. After a week the shop forman couldn't take him anymore and told him to go outside and clean and organize the pipe trailer. We have 7 semi trailers at a concrete loading doc for storage. The pipe trailer is lined from front to back with wooden shelves and wooden storage bins for black pipe, galvanized and copper fittings. In addition to that there's foam armaflex, cardboard boxes and cutting oil all over the place for the pipe threaders. Basically a big oily firetrap.
Cold January day and a few shop guys notice black smoke pouring out of the trailer. The jackass piled up a bunch of cardboard in the middle of the trailer and lit it on fire to stay warm. He was also working in the back of the trailer with the fire between him and the only way out! A few guys put the fire out and dragged his ass out of there. Of course he knew what he was doing and had everything under control and if the smoke got to be too much, he could slow his heart rate down to survive.
His final say on the matter...."I'm bringing newspaper tomorrow because it doesn't produce smoke".
Would full of nuts and it could always be worse.
He was finally let go after that.
