A quick test of intelligence.  Don't cheat!  Because if you did, the
test would be no fun. I promise, there are no tricks to the test.

Count them ONLY ONCE:
do not go back and count them again.

      ANSWER: There are six F's in the sentence.  One of average
       intelligence finds three of them.  If you spotted four, you're
     above average. If you got five, you can turn your nose at most anybody.

    If you caught six, you are a genius. There is no catch.
    Many people forget the "OF"s.  The human brain tends to see  them as V's and not F's. Pretty weird, huh?

 It fools almost everybody.
