While attempting to scream the 5th Law of the Navy for his squad leader, my brother encountered one of the meaner tricks of indoc day at the Naval Academy.
Halfway through, Mr. Smith came very close and said in his ear, "Peanut butter."
Mike didn't lose his composure, but kept shouting the law at the top of his lungs.
"Peanut butter. Peanut butter, peanut butter."
Mike started sweating more.
"Didn't you hear me? I said peanut butter."
He made it to the end and didn't break, he said, but it got worse later when they were all reciting the mission of the academy. He said the squad leader stood right in front of him, and smiled. Just smiled benevolently, as if to say, "I'm really proud of you not breaking earlier. Way to go. We're buds, right?" That, Mike said, was the toughest bit.
