From the Bulletin Our Bulletin for Sunday, June 6, 2004 had the following story.
       Some time ago, at  a  Midwestern  county  fair,  a
       contest was held to see which draft horse  could
       pull the heaviest load. One horse  pulled  a  sled
       with a load of 4,500 pounds. It was the  champion.
       The second-place  winner  managed  to  drag  4,000
       pounds. When the contest  was  over,  one  horse
       owner suggested that it would  be  interesting  to
       see how many pounds the top two horses could pull
       together. When the animals were harnessed together
       they were able to  pull  12,000  pounds!  Together
       they had pulled 3500 pounds more.
  

It seems to me that this story implies we can get more done when we work together.
