If the food you are to consume is anything more extravagant than beans on toast, then I would suggest this is a big no-no. I've always thought it a little insulting to the kitchen staff who have slaved to produce and serve a quality meal.
I'm not an old miserable git, with no sense of humour (some may disagree!) but save that sort of thing for squadron christmas parties!
The party piece from each diner sounds like a great idea. Even a shy Officer should be able to rouse the courage to stand up in front of 10 people!

PS. Korean rules = napkin round head and eating without the benefit of iron-mongery!
