YouTube montage celebrates 10 years of wasting your time

From screaming goats to Russian meteorites, YouTube has been making us unproductive since 2005. What better way to celebrate than with an artsy montage (below) featuring categories like "fails," "memes," and "animals" from YouTube's own Spotlight channel? It's set to Alpha Aerobics by Blackalicious, and will take you back to the day with Nyan Cat, Charlie the Unicorn and -- who could forget -- Kicked in the Head by a Train. Best of all, there's a full list of all 76 videos, which by my reckoning should let you blow a whole other day.
