My class, 04-76, was sweating through rifle drill along the seawall. SSgt. Wieckowski got so pissed at candidate J**k that he ripped the rifle out of his hands and threatened to beat him with it. We all thought he'd lost it and was actually going to induce physical harm on our classmate. He then turned and threw the rifle into the bay and told J**k he'd better go after it and either come back with it or drown trying. J**k obediently jumped into the bay and after being totally submerged for what seemed like forever, surfaced, gasping for air, with the rifle. The DI then screamed that he'd better get back in formation ASAP or he'd find himself as shark bait. We went from total horror and disbelief to almost hysterical laughter....until Wieckowski started threatening us with the same action.
