Of course, nowadays I'd write it in Perl 6, taking advantage of constants, aliasing, lazy mappings over infinite lists, string interpolation of code, automatic command-line interfaces, parameter defaults, countdown sequences, and indentable heredocs:
constant @bottles_of_beer :=
('No', 1, 2...*).map(->$n{"$n bottle{'s' if $n ne 1} of beer"});
sub MAIN(Int $max = 99) {
for $max...1 -> $n {
say qq:to<BURP!>
@bottles_of_beer[$n] on the wall,
@bottles_of_beer[$n].
Take one down, pass it around,
@bottles_of_beer[$n-1] on the wall.
BURP!
}
}
;-)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
