Managed it ? Scroll down only after you have counted
them, okay? Do you think there are three?









How many ? 3?
Wrong, there are 6 !!--no joke.
Read it again.
The reasoning behind is further down.





The brain cannot process "OF".
Incredible or what ? Go back and look again!!
Anyone who counts all 6 "F's" on the first go is
a genius. Three is normal, four is quite rare.
Send this to your friends-it drives them crazy.
