This is something I found out a couple days ago. Not the coolest shit ever but I thought it was neat. 

1.) Go to youtube. Select any video. Pause it once it starts.

2.) Click anywhere on the screen except on the video.

3.) Type 1980.

For some reason the old school Atari classic Missile Command will start playing at the top of the screen. I got a kick out of this, as I am old enough to actually remember when this game was the shit. Younger cats will shit on it, rightfully so, but fuck off anyway, this isn't for you. This could be old news but I just found out about it and thought it was neat so check it out if you want. You'll get bored in about 2 minutes but hey, what am I, your guidance counselor?
