Writing www.stackoverflow.com/admin.php
in the search bar of a web browser takes you to a random 10 hour YouTube video. Same for any site in Stack Exchange network.
My question is, why did Stack Exchange do it? Is it an Easter egg? The developers are just being funny? Did they want to offer programmers a link to take users to funny YouTube videos?
More, there is an Android game called "Nothing". If you perform some slides and taps in it, it takes you to that link.
