I can't believe it took me 37 years to discover my favorite sentence. 

Until now I did not have one.  Starting today, however, "Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo" is officially and forevermore my favorite.

In case you were wondering, it does in fact make sense.  And it helps me illustrate to clients that just because something might make logical sense it might not help you communicate your purpose or reach your goal.  (How many of you immediately understood the sentence to mean "Bison from Buffalo, New York, who are intimidated by other bison in their community also happen to intimidate other bison in their community"?  Anyone?)
