LOS ANGELES, Calif. -- Who Killed Scott Ruffalo?

That's a question that's been gnawing at some people around Hollywood since the brother of actor Mark Ruffalo turned up dead from a gunshot wound on December 8th.

We've seen the official Autopsy Report and it raises at least as many questions as it answers.

Known casually as Ping-Pong, celebs ranging from Susan Sarandon to Ed Norton have admitted their allegiance to the game. It hasn't been so in fashion since "Forrest Gump" in 1994.

In what could be her last interview before Americans head to the polls, the Alaska governor spoke with Billy Bush for Access Hollywood and "The Billy Bush Show" to talk about her "SNL" spoofs, her thoughts on celebrity political endorsements and her biggest regret along the campaign trail.
