For years I kept a beautiful gold-leafed copy of "The Prince" on my desk, prominently displayed to any visitor. Few noticed, perhaps fewer were familiar with the novel, but those that did and were got a huge kick out of it. It really relaxed those who "got it".
I stole the idea from a good friend who was a retired Coastie officer and a PhD physicist... with a great sense of humor.
PostScript: he's passed away now, but I feel truly honored to have counted him among my good friends.
