Lucy is having a garage sale, when she discovers an old cigarette lighter in the form of a lamp that she does not recognize. Its resemblance to "Aladdin's Lamp" leads her to go ahead and clean the lamp in the hope of selling it to Mary Jane. They make a wish, which comes true.
When Kim and Harry also get wishes fulfilled they believe that whoever is holding the lamp gets their wishes granted. When it gets accidentally thrown away at the office, Lucy and Harry search through the garbage bins to get it back.
