In easily the best April Fool of the day, YouTube has added a button to all videos that plays snippets of Darude's enduring dance banger 'Sandstorm'.
For starters, it works great on this video of Gandalf fighting the Balrog (you'll need to click through to YouTube to see the ♫ button).
The 1999 trance techno song has become an internet favourite in recent years, largely due to its offensively loud and repetitive bassline.
A video showing how the button works has now led to a chain of 'Sandception' videos, in which people film themselves hitting the button while watching someone hit the button while watching someone hit the bottom.
Every brand, publication, man, woman and child have been playing April Fools' prankstoday. You can read our round-up of the best ones here.Reuse content
