Schrödinger's Soprano
If I didn't know better, I would swear David Chase was actually a physicist creating an inside Schrödinger's Cat joke out of the last episode. Quantum mechanics meets pop culture, Tony is both alive and dead simultaneously.
I know most people, while watching the last scene, were thinking of the restaurant scene in the Godfather. I actually was thinking of the diner scene in Pulp Fiction. I kept waiting for Jules to pop up with a gun and start talking about the blood of the righteous, or whatever (I bet Tony knew what was in that damned suitcase).
