The appraisal

Made me cringe with laughter:

John Doe, my assistant developer, can always be found
hard at work in his cubicle. John works independently, without
wasting company time talking to colleagues. John never
thinks twice about assisting fellow employees, and he always
finishes given assignments on time. Often John takes extended
measures to complete his work, sometimes skipping
coffee breaks. John is an individual who has absolutely no
vanity in spite of his accomplishments and profound
knowledge in his field. I firmly believe that John can be
classed as a high-calibre employee, the type which cannot be
dispensed with. Consequently, I duly recommend that John can be
promoted to executive management, and a proposal will be
executed as soon as possible.

Once you read it slightly different:
