Kudos to our tipster SlyDante for finding this pretty amazing YouTube easter egg. Search for "bronies" on YouTube, start playing any video, then as it's playing, type "1980" (minus the quotes) on your keyboard. Not in the search field - just on the keyboard.
It turns into a playable game of Missile Command!
If you lose, the video is destroyed by incoming 8-bit ICBMs.
So - is your gamester friendship magic enough to protect Equestria's biggest fans?
