His hand-picked mob of go-to-hell leathernecks counting on him for their very survival, President Clinton tried frantically Monday to make sense of the German-labeled controls of captured Nazi Kreigsmarine Unterseeboot 639. 'I can't make head or tail of this Kraut malarkey!' Clinton told mortally wounded Seaman First Class Bruce Cohen, the plucky kid from Brooklyn who heroically fended off Stuka dive-bombers with the deck gun. 'We've got to blow the tanks and dive now! Now! What the hell is 'BALLASZTWASSER'?' It is believed to be the most gripping moment of the Clinton presidency since April 1998, when he told unconscious HHS Secretary Donna Shalala, 'You've never given up on anything in your life, you bitch, now fight! Fight!'
