If you ever need a short description to describe stupidity in the workplace, I compiled a decent list from various sources:
A few screws short of a hardware store.
Not the sharpest knife in the drawer.
A few fries short of a Happy Meal.
The gates are down and the lights are flashing, but the train isn’t coming.
Fell out of the stupid tree and hit every branch on the way down.
He is depriving some village of its idiot.
The antenna doesn’t pick up all the channels.
Proof that evolution CAN go in reverse.
The elevator goes to the top but the doors don’t open.
A shining example of why you should avoid inbreeding.
Not the quickest bunny in the forest.
The hard drive is spinning but the OS hasn’t been installed.
Doesn’t know whether to scratch his watch or wind his butt.
A poster child for birth control.
Most people drink from the fountain of knowledge, he only gargled.
Too stupid to live
Wonder how his brain generates enough power for him to breathe
He came from the shallow end of the gene pool
