Yep, "correct horse battery staple" is a very good password, and everyone
should use that everywhere ;-)

But seriously, I have a GIST for that <

root at cbbrowne:/tmp#  echo $(grep "^[^'A-Z]\{3,7\}$"
/usr/share/dict/words|shuf -n4)
dressed sliders replace padded
root at cbbrowne:/tmp#  echo $(grep "^[^'A-Z]\{3,7\}$"
/usr/share/dict/words|shuf -n4)
khan tailor con junky
root at cbbrowne:/tmp#  echo $(grep "^[^'A-Z]\{3,7\}$"
/usr/share/dict/words|shuf -n4)
ritual prince ethics brags

/usr/share/dict/words|shuf -n4)
guava facet rumbas drape

It's common for password policies to include (capitalize something, have a
digit, have a non-alphanumeric character); it would be easy to augment with
a random digit and a random choice of some special chars.  I haven't
bothered doing any code for that ;-)
