No man is an island. From time to time, we all find we’ve gone as far as we can go on our own. Therein lays the beauty of teamwork: a helping hand to pick you up and see you through to the end. To celebrate the joy of working together, we’ve compiled the definitive list of the best teams ever assembled, along with what each of them has to teach us. We made our picks from all walks of life, from sports to space and from fictional to factual. Enjoy.
