Ask HN: Favorite quotes from manpages/documentation?

In another thread, someone pointed out the hilariousness of the descriptions of the true(1) and false(1) commands in their respective manpages:

  true - do nothing, successfully
  false - do nothing, unsuccessfully

Another manpage that I like is hdparm(8) because of the sheer amount of uppercase warnings like "VERY DANGEROUS, DON'T EVEN THINK ABOUT USING IT."

Are there any other gems in those manpages that I may have missed?
