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