Yeah Zach, we have talked about this one sooooo much in the past, I feel like I know where this might be going....

class Bottles

  def sing
    verses 99, 0
  end

  def verses start, finish
    result = ""
    start.downto finish do |i|
      result += "#{verse i}\n"
    end
    result
  end

  def verse number
    case number
    when 0
      "No more bottles of beer on the wall, no more bottles of beer.\n" \
      "Go to the store and buy some more, 99 bottles of beer on the wall.\n"
    when 1
      "1 bottle of beer on the wall, 1 bottle of beer.\n" \
      "Take it down and pass it around, no more bottles of beer on the wall.\n"
    when 2
      "2 bottles of beer on the wall, 2 bottles of beer.\n" \
      "Take one down and pass it around, 1 bottle of beer on the wall.\n"
    when 3..99

...and F#...cause...I'm an asshole
