Upsidedown Youtube

Today went to Youtube and when looking at a vid everything was upside down. And there was a mysterious blue box on the right. However I click is and pretty much scrolled down directly because I know today is Aprils Fools day!

However they give funny reasons why they made it possible to read upside down, like test proved that a screens upside down give better quality and or if you have water in your ears to turn your head. However on the lowest part they say April fools and how to shut down this upside down option. However they used allot of effort to do this because I have seen them being busy adding this for a couple of hours till they finally were done. Have a nice April Fools day!!!
