Got a day to spare? Because Pharrell's music video for the song "Happy" will take up exactly that.

Hailing from the "Despicable Me 2" soundtrack, "Happy" repeats throughout the 24-hour footage, following the fancy footsteps of Skateboard P and friends throughout Los Angeles. Cameos come from Steve Carrel, Tyler The Creator, Magic Johnson, and many other smiled strangers.
