Actual lines from U.S military Officer Efficiency Reports:
Not the sharpest knife in the drawer
Got into the gene pool while the life guard wasn't watching
A room temperature IQ
Got a full 6 pack, but lacks the plastic thingy to hold it all together
A prime candidate for natural de-selection
Bright as Alaska in December
Gates are down, the lights are flashing, but the train isn't coming
So dense, light bends around him (I love this one)
If he were any more stupid, he'd have to be watered twice a week
Wheel is turning but the hamster is dead
Extracts from Royal Navy and Marines Officer fitness reports:
His men would follow him anywhere, but only out of curiosity
I would not breed from this officer
He has carried out each and every one of his duties to his entire satisfaction
He would be out of his depth in a car park puddle
This young lady has delusions of adequacy
This medical officer has used my ship to carry his genitals from port to port, and my officers to carry him from bar to bar.
Since my last report he has reached rock bottom and has started to dig
She sets low personal standards and then consistently fails to meet them
He has the wisdom of youth and the energy of old age
Works well when under constant supervision and cornered like a rat in a trap.
This man is depriving a village somewhere of an idiot"
