Is Brian From Family Guy Really Dead? [POLL]

A stunning Family Guy episode Sunday night, as Brian the dog got hit by a car and died.  Some Family Guy fans are signing petitions to bring back Brian...some just flat out don't believe his death is permanent.  Stewie destroyed his time machine in the episode, but maybe somehow it can be rebuilt?

The shows producers insist it is not a stunt...they say that they needed to shake up the show a little bit.  The Griffins already got a new dog named Vinnie (voiced by Tony Sirico, formerly Paulie from the Sopranos).  TMZ is reporting that Brian's death seems to be permanent, as Sirico has been signed on for at least 6 more episodes.
