here's another example, using downto


beer = 99
beer.downto(0) do |b|
   puts "#{b} bottles of beer."
   puts "take one, drink it."
   puts "#{b - 1} left."
end

but that needs an if statement to take care of the negative beer!

beer = 99
beer.downto(0) do |b|
   puts "#{b} bottles of beer."
   if b > 0 do
     puts "take one, drink it."
     puts "#{b - 1} left."
   end
end


Of course it could be shorter still. but that's for you to toy with.
