In the Navy, Joey Bag A Donuts

I have not had a donut in years and my Shipmates seem to think this is hilarious. That not eating a donut is not fitting for a Sailor. That Sailors should be eating donuts! Whenever the subject comes up, I feel the same way Joey Bag A Donuts does in this picture. The Navy preaches a culture of physical fitness but prizes eating fried balls of sugared dough?
