In one of the weirder casting updates of the fall 2012 TV seasons, singer Tom Waits will appear on The Simpsons. But not to sing!
NME reports the gravelly-voiced musician will introduce Homer Simpson to the survivalism movement, called "preppers," who prepare for Earthly disasters such as the impending apocalypse. Preppers stock up on canned goods like the Coupon Queen, learn how to build shelters, and perfect skills to fend off zombies/packs of wild dogs.A half-assed Google search suggested that Tom Waits is not actually a survivalist and that The Simpsons writers are just taking creative liberties.
It's also probably just as well he is not singing. I would hate to have to hear Homer explain Pasties And A G-String to Lisa Simpson.
