Or imagine a While You Were Out segment. Liz and Roger decide to surprise Barnabas (it seems that there were always sections of that house that were never finished - there's that wall section in the foyer with the hole and ripped wallpaper). He comes back and discovers they turned his coffin into a planter (with garlic cloves growing in it) or something. And Josette's room converted into a late-sixties/early-seventies rumpus room with Peter Max posters, black light bulbs, and a lava lamp where the music box use to sit.
