Once again Jimmy Fallon has taken on a YouTube memory of old and given it the Tonight Show treatment that only Fallon can. 

If you remember correctly, previous incarnations of Fallon's dance history lessons have involved Will Smith and Justin Timberlake and this time it's the turn of dads in honour of Fathers Day, and so the 'Evolution of Dance' becomes the 'The Evolution of Dad Dancing', this time with a little help from New Jersey Governor Chris Christie. We've witnessed a dad do at least one of these.
