When she's forced to attend a family affair, Sabrina sends a clone to Harvey's party, where the simple-minded stand-in (who can only speak three sentences) agrees to streak naked in order to liven up the festivities. Meanwhile, the real Sabrina desperately tries to ditch her relatives: an obnoxious socialite and her brat of a daughter, whose hobby is putting people she dislikes into jars. Knowing Harvey plans to dress as James Dean, Sabrina muses about the real star, but when her aunts give her a special Halloween present of a half hour with the dead person of her choice, she opts for her beloved grandmother instead, because "Halloween is really about family."
