The Army Airborne major was used to harassment from Air
Force fliers about crazy Army paratroopers jumping out of 
perfectly good aircraft.  "Obviously the Air Force knows there's
no such thing as a 'perfectly good aircraft,'" the irritated 
officer finally countered one afternoon, "because they pay 
you bastards four times as much to stay in one as the Army
pays its men to jump."

"You've got it all wrong, Major," an Air Force sergeant 
replied.  "The Army figures anyone stupid enough to jump 
out of an airplane voluntarily is gonna be too dumb to bitch
about the salary."
