Thank you.

I used a perl script called delirium to do that. It's a text filter that works on STDIN/STDOUT. It also uses HTML::Parser so it won't mess up your tags (just your content ;). I've put it up here at perlmonks.org, and it's also in the CVS repository for Free Software at my werk. (Just hit the link below).

Be glad that I didn't make the whole article delirious.

Obviously written by a Sandman fan :)

If I can suggest one small tweak that would make it look even more like the way that Delirium speaks, perhaps you could get it to add in <sup> and <sub> tags at random.

print "Just another Gaiman fan\n";
