Alright buddy? How you feeling? Bit down? Well we have the solution: watch pint-sized popstar Pharrell Williams bopping around downtown LA singing new song Happy and we guarantee those endorphins will start whizzing round your body.
The video for the track, which features on the Despicable Me 2 soundtrack, does exactly what it says on the tin. It's crammed full of smiley people just kicking back and loving life.
Keep your eyes peeled for cameos from the likes of Kelly Osbourne, Jamie Foxx and Jimmy Kimmel.
Pharrell has also created the world's first ever 24-hour music video, 24hoursofhappy.com, which has even more joyful people lip-syncing to the song and cutting some serious shapes.
Stick this on, turn the volume up and have your own little lunchtime rock-out sesh on us.
