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.
