When I was a lad and still wearing a (light) blue uniform I was lucky enough to attend the RN advanced drinking and partying course at Greenwich. Great fun was had by all. I did enjoy my immersion in Jack-speak and I must admit to having held on to a few choice phrases even now - run ashore being one of them. All very amsusing stuff, but nowhere near as hilarious as the First Lieutenant having to salute and receive salutes from warships passing up and down the Thames. Of course, as an air force type I had to concede that we hadn't been around long enough to have traditions, we had merely developed some bad habits.
