Three men are sitting stiffly side by side on a long commercial flight. After they're airborne and the plane has leveled off, the man in the window seat abruptly says, distinctly and confidently, in a low voice, "General, United States Army, retired. Married, two sons, both surgeons." After a few minutes the man in the aisle seat states through a tightlipped smile, "General, United States Air Force, retired. Married, two sons, both judges." After some thought, the fellow in the center seat decides to introduce himself. With a twinkle in his eye, he proclaims, "Master Gunnery Sergeant, United States Marine Corps, retired. Never married, two sons, both Generals!!!"
