Woody, that tired dog reminds me of Basic & AIT in the USA INF... whenever tired troops would start to nod in those occasional classroom courses, the cadre would slam the table in front of 'em and the troops would have to stand up on one side of the room, lol. Troops were SO TIRED from long days & weeks of training, they'd fall asleep ANYWHERE at any given time, lol. I remember sleeping aboard a crowded deuce-and-a-half one time, with the truck jolting & bouncing down a rough tank trail... it was crazy, that's how tired we were. Even a short "power nap" would help...
