... rare tree, rattlin' tree.

Ever heard "Rattlin' bog" before? If not, google for it, a nice example of recursive song ;) And here's a script that will spew out lyrics for it.

Forgive me if these are not 100% correct, I'm not an English native speaker. 

#!/usr/bin/perl -w

@slowa = (
        [ "bog",                "in" ],
        [ "hole",               "in" ],
        [ "tree",               "on" ],
        [ "bough",              "on" ],
        [ "limb",               "on" ],
        [ "branch",             "on" ],
        [ "twig",               "on" ],
        [ "leaf",               "on" ],
        [ "nest",               "in" ],
        [ "bird",               "in" ],
        [ "egg",                "in" ],
        [ "yolk",               "in" ],
        [ "chick",              "on" ],
        [ "wing",               "on" ],
        [ "feather",            "on" ],
        [ "flea",               "on" ],
        [ "eye",                "on" ],
        [ "germ",               "on" ],
        [ "amoeba",             "on" ],
        [ "paramecium",         "on" ],
        [ "virus",              "in" ],
        [ "subatomic particle", "in" ]
);

while($foo = $slowa[++$i][0] ) {

   # refren
   print "Oh'ro the rattlin bog / ",
         "and the bog down in the valley o'\n",
         "Rare bog, rattlin bog / ", 
         "and the bog down in the valley o'\n\n";

   push @spiewam, $foo;

   print " \u$slowa[$i-1][1] that $slowa[$i-1][0] there was a $foo\n",
         " Rare $foo, rattlin' $foo\n\n";

   $j = @spiewam;
   foreach $bar (reverse @spiewam) {
           print("\t", ( map {$j == @spiewam ? ucfirst :
                 "And $_"} $bar) , " $slowa[$j-1][1] the ", 
                 "$slowa[$j-1][0],\n");
           $j--;
   }

   print (($i == @slowa-1 ? "\tAnd t" : "\tT"), 
         "he bog down in the valley-o'.\n\n");
