I heard a pretty funny joke today...
A Marine is someone belonging to a special forces branch of the Army. They are not a self standing section of the military, they are under the command of the US Army, despite their claims.
They happen to use Naval equipment and deployment vehicles on occassion, so a problem occured.
You see, despite being under the direct control of the Army, they constantly use Navy resources.
This makes them part homosexual.
So to correct this half-problem, the Army likes to (as having absolute disgust for anything homosexual, like the Navy, or pansies, like the Airforce) pretend the Marines are actually their own specific, uncontrolled branch of the Military. On par with the Army, Navy and Airforce.
So remember that Marines, you belong to us. Its just...we dont love you enough to except who you really are deep inside.
;P
