Lucy goes to an auction and somehow winds up winning the bid for a vintage oil painting for $50. She believes it to be valuable but everyone tells her it is worthless. So Lucy goes to the home of a former client and well-known art connoisseur, Vincent Price, to get it appraised.
Unknown to Lucy, Price has remodeled a part of his home as a mad scientist set for his upcoming movie. Price mistakes Lucy for an actress in his new horror movie and proceeds to rehearse a scene for his latest victim in his newly created evil laboratory.
In the end, Price strips the painting to reveal a "No Ball Playing Allowed" sign underneath, and makes Harry buy it.
Special Notes: Cut out of the syndicated version of this episode is the entire scene with Kim and Craig fretting over their mother's visit to Price's home.
