At OTU the Commandant had a habit of wandering through the lines after lectures, when we were sitting around outside our rooms polishing boots etc, usually wearing footy shorts, singlets and general muck order. Of course, as soon as he appeared we had to leap up and stand fast. On these expeditions, he was usually preceded by his pet labrador dog.
One afternoon the dog appeared at on end of the lines, so everyone stood fast. The Commandant appeared at the other end of the lines, to find a dozen occifer cadets paying compliments to his dog. "You, you, you...etc, take an extra."
