The British Military writes OFR's (officer fitness reports). The form used for Royal Navy and Marines fitness reports is the 206. The following are actual excerpts taken from people's 206's...

"When she opens her mouth, it seems that this is only to change whichever foot was previously in there."
"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."
"Technically sound, but socially impossible."
"This Officer reminds me very much of a gyroscope - always spinning around at a frantic pace, but not really going anywhere."
"This young lady has delusions of adequacy."
"When he joined my ship, this Officer was something of a granny; since then he has aged considerably."
"Since my last report he has reached rock bottom, and has started to dig."
"She sets low personal standards and then consistently fails to achieve them."
"He has the wisdom of youth, and the energy of old age."
"In my opinion this pilot should not be authorized to fly below 250 feet."
