Idiocy combined with stubbornness is a dangerous combination in any workplace.
At one of my early jobs, I worked on a project for the VP. He asked me to have the project done a certain way and I told him it was wrong.
He got mad at me despite my trying to reason with him and finally said "Look, I'm the boss here, so you listen to what I'm saying, stop arguing and just do it!"
A month later I got called into his office and he was mad, asking me why I did such and such when it was wrong.
I reminded him "you ordered me to do it even though I told you it was wrong!"
His response: "You should've known better than to listen to me!"
I had to agree with him on that!
