Spider-Pig, Spider-Pig — you loved him in the movie, you’ve hummed his theme song, now see him on the small screen! Homer’s porcine BFF dips his hoof into season 19, as do a slew of guests: Jon Stewart, Stephen Colbert, Dan Rather, Jack Black, Matt Dillon, Maya Rudolph, Steve Buscemi — heck, there’s even a Frasier reunion when John Mahoney joins Kelsey Grammer and David Hyde Pierce in a Sideshow Bob story line. Also look for Homer and Marge to moonlight as assassins in a ”Treehouse of Horror” Mr. & Mrs. Smith parody, as well as a run for president by…Ralph Wiggum? Says executive producer Al Jean: ”There’s a joke where [Dan Rather] asks Ralph what he thinks and Ralph says, ‘Mommy, the big man scared me!’ and [Rather] goes, ‘Exactly what George W. Bush said.”’
