but you are on duty today and your alarm clock starts beeping , and its six-thirty and muster is at seven so you shower and shave and dress putting on the bell bottoms and the socks and the boots and the shirt and the cap , and then you take off the shirt and reach into the coffin locker and pull out one of the flying squad turtlenecks and pull it on and then go to the mess decks to eat walking one two three four and duck and up down the passageway and over the kneeknockers in the kneeknocker rhythm one , two , three , four big steps and duck and up and over and one , two , three , four big steps and duck and up and over and through the hatch .
