Hey
The picture explains it self. This works better on 4chan because you can't fake it, once you post you have the number but well this is just the internet and we shouldn't take it to serious.
Now to get your number just go to random.org and generate a number between 1 and 9999999999.
use the result for the picture game.
By the way, if you know a better way then feel free to add it here.
