HIDE the kids – “The Simpsons” annual “Treehouse of Horror” is back Nov. 7.

In this year’s 15th edition, which as usual airs a week after Halloween, Lisa and Bart take on a Jack-the-Ripper style serial killer loose in Victorian London in “Four Beheadings and a Funeral.”

Meanwhile, baby Maggie is shrunk down into a pill and swallowed by Mr. Burns. The family tries to rescue her a la “Fantasic Voyage,” but Homer gets trapped FOREVER inside his boss’ belly.

And in “The Ned Zone,” Ned Flanders gains the power to see people’s deaths.
