I'll just pop this here:

  $ cat `which xkcdpass`
  #!/bin/sh
  perl -MCrypt::XkcdPassword -E 'say Crypt::XkcdPassword->make_password for 1 .. 10'

For the chumps (like me) who don't know how to get the perl mcrypt module:

    sort -R /usr/share/dict/words | head -n 4

Even shorter: (and much faster!)

    shuf -n 4 /usr/share/dict/words

Somewhat more seriously, Diceware works pretty well too as a low-tech, high-quality password generation method:

(My only complaint is that a lot of words in the standard wordlist are pretty obscure.)

we wrote this one at my company. It uses your mouse movements as a seed for the random number generator.
