From the Air Force Enlisted's Book of Knowledge comes this passage:
In the beginning was The Plan. Then came the Assumptions. The Assumptions were without form. The Plan was completely without substance and darkness was upon the face of the airmen, and they spoke amongst themselves, saying "It is a crock of sh*t and it stinketh".
And the airmen went unto their supervisors saying, "It is a pail of dung and none may abide the odor thereof," and the supervisors went unto their Branch Chiefs saying, "It is a container of excrement and it is very strong, such that none may abide by it."
The Branch Chiefs then went unto the Commanders saying "It is a vessel of fertilizer, and none may abide it's strength." The Commanders spoke amongst themselves, saying to one another, "It contains that which aids plant growth and it is very strong."
The Commanders then went to their Deputies saying, "It promotes growth and it is very powerful."
The Deputies went unto the Wing Commander and said "This new Plan will actively promote growth and efficiency of the Wing and in weak areas in particular"
The Wing Commander looked upon the Plan, and saw that it was good and the Plan became Policy. This is how sh*t happens, so sayeth the Enlisted Guru.
