Google needs to stop coming up with ways to waste time. I’m good enough at doing so without help. 
Easter Egg of the Day: YouTuber neoconnor1111 was tipped off by his brother to this rather nifty YouTube Easter Egg: Pausing any video and holding down the Left key will transform the buffer wheel into a full-fledged Snake game, which you can then play while the video runs in the background. (Doesn’t seem to work with embeds, only on YouTube proper.)
