If you haven't watched last night's Sopranos yet, stop reading now! Ralphie Cifaretto the wiseguy played by actor Joe Pantoliano finally met his maker on Sunday's episode. And in case you were wondering, Tony (James Gandolfini) did the deed. Incidentally, while chatting it up with Conan O'Brien on a recent Late Night, Pantoliano bet the host $10,000 that his alter ego would survive the season. No word if O'Brien plans to collect.
