Alison Arngrim used to make out on set with Steve Tracy to unnerve Melissa Gilbert
Playing on Gilbert’s discomfort with boys and affection, Alison Arngrim used to make out with actor Steve Tracy, who played her husband, Percival. This wasn’t any sort of peck-on-the-cheek, either. They were mackin’ down like teenagers. Since their scenes required it, they figured the practice made only them better.
