Any thoughts would be appreciated :wink:

Instead of using a 'while' loop (unless that's what the book is
teaching you) I think the following is more Ruby-esque:

99.downto( 1 ) do |num|
  puts "#{num} bottles of beer on the wall, #{num} bottles of beer,"
  puts "take one down, pass it around,"
end
puts '0,Bottles of beer on the wall ;)'

Note the use of string interpolation also instead of .to_s and +
