For the culturally unaware... The Herndon Climb is an annual tradition at the Annapolis Naval Academy in which members of the freshmen class, AKA "plebes," climb a lard-covered monument to retrieve the Plebe 'dixie cup' hat and replace it with an upperclassmen's hat, marking the end of wearing freshman headgear and moving up to headgear more like a U.S. Naval officer.
But really, it's just about getting nearly naked and climbing a wet, greasy pole. For America.
