The Navy Chief noticed a new seaman and barked at him, "Get over here! What's your name sailor?"
"John," the new seaman replied.
"Look, I don't know what kind of bleeding-heart pansy crap they're teaching sailors in boot camp nowadays, but I don't call anyone by his first name," the chief scowled. "It breeds familiarity, and that leads to a breakdown in authority. I refer to my sailors by their last names only; Smith, Jones, Baker, whatever. And you are to refer to me as 'Chief'. Do I make myself clear?"
"Aye, Aye Chief!"
"Now that we've got that straight, what's your last name?"
The seaman sighed. "Darling, My name is John Darling, Chief."
