We're not sure where to file this one. Under "B" for "bizarre", "P" for "pointless", "W" for "why" or maybe even "A" for "awesome".
We just received word of a secret "easter-egg" hidden within YouTube. Start a video on the site (it seems you have to actually be on YouTube, rather than watching an embedded video) and then left-click the video and hold the left and up arrow keys.
You can then play Nokia 3310 style Snake with the video playing in the background.
It seems to work with any video.
I think after playing for 10 minutes, we'll actually go for "P". After all, it doesn't even keep score.
