Like clockwork, we’ve regrettably reached the time of year when we have to suffer through a Christmas-themed episode of Zombie Simpsons.  “The Fight Before Christmas” (har, har) has Martha Stewart and Katy Perry as guest stars, though I assume that they will be as forgettable as the other celebrity voices this season.  Here’s Simpsons Channel with the blow-by-blow:

Disappointed that she is alone spreading the holiday cheer, Marge sends a letter to Martha Clause (Martha Stewart) to help her save the family Christmas. Martha comes to the rescue and transforms the house into the North Pole chalet Marge has always dreamed of, but when the family is noticeably absent from the perfectly trimmed holiday home, she realizes that it’s Homer and the kids who make the holidays special. Meanwhile, the Simpsons get ready to sneak away for a tropical holiday vacation in Hawaii, but surprise visitors Mr. Burns and Moe’s new friend, Katy Perry (guest-starring as herself in a special live-action sequence) delay their getaway.

So, the writers of Zombie Simpsons have decided to give us a live-action sequence, two guest stars, a contrived morality tale about the meaningless of materiality, and a travel episode rolled into one.  Wouldn’t a lump of coal have been preferable?  I guess the kitchen sink approach is somewhat novel in its utter lack of focus, though I suppose if Katy does the following, it is likely many will overlook the the episode’s inherent and unavoidable flaws:

Bouncy bouncy.
