"Treehouse of Horror XII" includes Pierce Brosnan as the voice of a computerized house that falls for Marge; a Gypsy's curse bringing bad luck to Homer's loved ones; and Bart and Lisa as competing wizards, with Bart enlisting help from a dark source.

Moe gets more depressed than usual and renovates his tavern. He then kicks the old gang out and Homer opens a bar in his garage so the gang can have a place to hang out and fit in.
