OK, if you're not all exhausted by the Sopranos talk and examination of that final scene, let me bring up yet another take on the episode, via a friend of TV critic Roger Catlin at The Hartford Courant.

During the scene in the safehouse in the episode, there an an episode of The Twilight Zone playing on the television. An alert viewer figured out that it was the 1963 episode "The Bard," where a TV writer gets help from the ghost of William Shakespeare, who gets angry at the meddling from advertisers and the network and eventually punches an actor (Burt Reynolds).
