About 12 minutes into the movie, Morticia, Granny and Margaret are looking for things for auction when Morticia hands Margaret a finger trap from the court of Emperor Wu. As they are casually talking you see Margaret struggling with the traps on her index fingers. The camera flashes to Morticia and back to Margaret and she's holding it on the outside again. Then she inserts her fingers and you hear it snap shut on the fingers where she again begins to struggle with them.
