-Q:	How much does it cost to ride the Unibus?
-A:	2 bits.
+You will get what you deserve.
 
 
-Training is everything.  The peach was once a bitter almond; cauliflower is
-nothing but cabbage with a college education.
+The true Southern watermelon is a boon apart, and not to be mentioned with
+commoner things.  It is chief of the world's luxuries, king by the grace of God
+over all the fruits of the earth.  When one has tasted it, he knows what the
+angels eat.  It was not a Southern watermelon that Eve took; we know it because
+she repented.
