At the one DS Fest I attended, during a question-and-answer session with cast members up on the stage, an audience member did an absolutely hysterical tongue-in-cheek "question" about props moving about. She did a short schtick about the piano in the drawing room in particular which had everyone, including the cast members, in stitches. When she was finished, everyone applauded at her witty, hilarious routine. She should've been on Leno.
