use Perl

Once you use bogofilter, an interesting perl / shell command is :

strings -n3 ~/.bogofilter/spamlist.db | \
perl -lne 'END{print"@x"}for$i(0..19){int rand$. or$x[$i]=$_}'

This outputs a 20-word burroughsian cut-up of the received spam. Ideal to feed the phosphor(1) hack of xscreensaver(1) (although the random text may contain profanity.)

Here's a random sample :

Pure computer-generated poetry, uh ? This could even be turned into haikus.
