You know how google likes to hide things (like googling ‘do a barrel roll’ will cause the website to do a barrel roll)
Well, they hid something in youtube. You can make all the comments turn into leet.
To do it, you click 3 times anywhere on the page, then hit these keys: ‘1 3 3 7’
To get rid of it just refresh.
Apparently 1980 starts a game too. But it’s never worked for me and I can’t even remember if they’re the correct numbers.
I believe those are the numbers. I found out about this just a few days ago.
Wow, it really does start a game o.0
I just tried it again, finally worked! I sucked at the game though. 
Cool! Reminds me of the Google search for “Zerg Rush”.
