This is the part of the code that I was interested in. I do believe that you can make this much simplier (and faster) with one SQL call: 

    $tth=$dbh->prepare("select koan from zen order by rand() limit 1")
+ 
        or die("Can't connect: ",$dbh->errstr);

    $tth->execute;
    $koan = $tth->fetchrow_array;

("order by rand()" is mentioned in chapter 7 of the mysql doc, and I used this trick for a random quote generator of my own.)
