  class << self
    def parse_with_us_format(date, *args)
      if date =~ %r{^\d+/\d+/(\d+)$}
        Date.strptime date, "%m/%d/#{$1.length == 4 || args.first == false ? '%Y' : '%y'}"
      else
        parse_without_us_format(date, *args)
      end
    end
    alias_method_chain :parse, :us_format
  end
