I stumbled across these today. http://en.wikipedia.org/wiki/Augustine's_laws Truthful and funny at the same time.
Law #16 seems appropriate with regard to this topic. "In the year 2054, the entire defense budget will purchase just one aircraft. This aircraft will have to be shared by the Air Force and Navy 3-1/2 days each per week except for leap year, when it will be made available to the Marines for the extra day."
The chart is from the Wiki page.
