I came across these line while reading Joseph Heller's novel Catch-22 yesterday:
"Major Major had been born to late and too mediocre. Some men are born mediocre, some men achieve mediocrity, and some men have medicrity thrust upon them. With Major Major it had been all three. Even among men lacking all distinction he inevitably stood out as a man lacking more distinction than all the rest, and people who met him were always impressed by how unimpressive he was."
