Army General, Marine General, Air force General, and a Navy Admiral were touring their respective bases.
Air force general says to an airman... airman, walk into that airplanes jetwash... and the airman does it and gets thrown across the flight line. General says... that's balls.
Army general tells one of his privates... private, go run that obstacle course faster than you've ever run it... GO! Private runs the course in record time. General says... now that's balls.
Marine general tells one of his privates... private, go conquer that hill, now... GO! The private conquers the hill, on his own. General says... now that, gents... is balls.
Admiral waves at a seaman up in the stacks of the ship... says, hey seaman... jump off that yardarm! Seaman looks at the admiral and screams back... FU*K THAT, ADMIRAL! Admiral says... Gentlemen... THAT is BALLS!
