The logic made me laugh :)

    def random_reply
      reply = Reply.order("RAND()").first.content

      # if the conversation is getting long, start injecting hipster sentences to the end...
      if self.conversation.emails.count > 10
        reply << " #{Faker::Hipster.sentence}"
      end
      return reply
    end

P.S.: It's a simple Rails app
