Generate an XKCD #936 style 4 word password

jot 4 | awk '{ print "wc -l /usr/share/dict/words | awk '"'"'{ print \"echo $[ $RANDOM * $RANDOM % \" $1 \"]\" }'"'"' | bash | awk '"'"'{ print \"sed -n \" $1 \"p /usr/share/dict/words\" }'"'"' | bash" }' | bash | tr -d '\n' | sed 's/$/\n/'
So I use OSX and don't have the shuf command. This is what I could come up with. This command assumes /usr/share/dict/words does not surpass 137,817,948 lines and line selection is NOT uniformly random.
