READ this sentence:
 
  FINISHED FILES ARE THE RE-
  SULT OF YEARS OF SCIENTIF-
  IC STUDY COMBINED WITH
  THE EXPERIENCE OF YEARS.
 
Now count aloud the F's in that sentence.  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 almost anybody.  If you caught 
six, you are a genius.  There is no catch.
