My first time writing Ruby — worked for a half hour on the introductory exercise from "99 Bottles of OOP." All tests pass!

bottles.rb

class Bottles
  def song
    verses 99, 0
  end
  def verses(start, stop)
    start.downto(stop).map {|v| self.verse v}.join("\n")
  end
  def verse(num)
    "#{self.bottle_text(num).capitalize} of beer on the wall, #{self.bottle_text num} of beer.
#{self.next_action num}
"
  end
  def next_action(num)
    if num >= 1
      "Take #{num == 1 ? "it" : "one"} down and pass it around, #{self.bottle_text (num - 1)} of beer on the wall."
    else
      "Go to the store and buy some more, 99 bottles of beer on the wall."
    end
  end
  def bottle_text(num)
    if num == 0
      "no more bottles"
    elsif num == 1
      "1 bottle"
    else
      "#{num} bottles"
    end
  end
end
