'Tis the 30th Season/Gags

Couch gag
Marge, Lisa, Maggie and Bart are upside down on the cieling. When wampa-Homer comes to attack them, Bart uses the force to grab the light saber and cut its hand. The monster reattaches it and hugs Marge, and they all say "Merry Christmas", and then the wampa's hand comes off once again.
