Hint:
look at his statuses
example:
Danny Rodriguez, Mor Gadi Symons, Veronica Larios and 167,360 others like this.
The more single statuses he has with these numbers - the higher the talking about... so its single statuses that got viral.
Then its not overnight - its a steady growth as you can see here:
fb.com/pages/Poop/307400006046956?id=307400006046956&sk=likes
And last but not least - he likes a lot of other pages - so I guess its a network and they just decided to promote this page more or he started promoting it on those pages on his own...
Last possibility that pops (not poops) in my mind right now is that he got more suggestions by facebook...
They are very generous with suggestions when it comes to 'shitty countrys' in terms of revenue.
