Subject: human-readable listing of array elements

This took me less than a minute to write, but I don't know if it's as
elegant as it could be. Are there more "Ruby-like ways(tm)" to write
this?

def stringify array
  return array[0] if array.size == 1
  string = ""
  array.each_with_index do |element, index|
    case index
      when array.size - 1 # last item
        string += " and #{element}"
      when 0
        string += "#{element}"
      else
        string += ", #{element}"
    end
  end
  string
end
