    You didn't provide a mechanism that changes "bottles" to "bottle" when $beer==1.

    Oh, and $beer should be decremented at the moment you say "take one down".

    You'll probably be interested in node 99 Bottles Of Beer (can't we do better).

    Just cause I'm chirpy today, I'll reprise my not-very-terse solution:

    #!/usr/bin/perl $bc = abs(shift || 100); $p_sub = sub { 'Take ' . (shift == 1 ? 'it' : 'one') . " down, pass it around,\n" }; $b_sub = sub { 'bottle' . (shift != 1 ? 's' : '') }; $c_sub = sub { $_ = shift||'No'; "$_ " . &$b_sub($_) . ' of beer' }; $w_sub = sub { &$c_sub(shift) . " on the wall"; }; $sub = sub { $_ = shift; print &$w_sub($_), ",\n", &$c_sub($_), ",\n", &$p_sub($_), &$w_sub(--$_), ".\n\n" }; map(&$sub($_), reverse(1 .. $bc)); print "burp!\n";
