To digress a tad, the bacon banjo is the bastard offspring of the egg banjo - the squaddie's fast food of choice for generations. A proper egg banjo is two slices of white bread with a fried egg in between with a runny yolk.
The name comes from the inevitable moment that comes when the yolk is broached; the eater stands there with left arm outstretched holding the remains of the egg banjo while the right hand frantically frails to get the yolk off the front of one's windproofs.
According to legend there was a choddy wagon on Mount Olympus specifically to serve the gods the finest egg banjoes.
