What do mom-dancing, hashtags and children's instruments have in common? They're all topics that Jimmy Fallon, with his one-of-a-kind ingenuity and enthusiasm, was able to mine for big laughs – and, once they hit the Web, big views.
Possibly more than any other show, Fallon's Late Night understood the science of making comedy bits go viral. The formula was easy to explain, but hard to master: Take a celebrity, give him or her a trending topic and find a cutesy, nostalgic spin, then hopefully watch the views roll in.
