Yes, it involves the song ‘Happy’.

In 2012 the United Nations decided the world needed a universal day to celebrate the common pursuit of happiness. A year later, March 20 was declared the first International Day Of Happiness. Happiness Day didn’t exactly catch on like wild fire, but that’s never been a problem for Pharrell‘s massive hit ‘Happy‘. Now the UN have enlisted Pharrell as an ambassador for the 3rd annual Happy Day, reports Rolling Stone.

In addition to encouraging people to sign the Live Earth petition to get global leaders to adopt new climate change accords, the producer will build a massive Pandora playlist with songs to inspire happiness. He will also be leading something they’re calling a “global happiness party” which encourages people to upload .gifs of themselves all over the world to craft a new music video to ‘Happy’. It all goes down this Friday.

In other (decidedly unhappy) news Pharrell and Robin Thicke were recently ordered to pay $7.4 million to the family of Marvin Gaye after the lengthy infringement battle over ‘Blurred Lines’ came to a close.
