The switching of actresses in the role of Rosie mimics the actual handing over of the real-life 'Rosie's Bar' during the Korean War from mother to daughter. Alan Alda became aware of this when he received a letter from the real 'Rosie Jr.' about the incident in the early 1980s, a copy of which is available in the book The Last Days of M*A*S*H by Alan and Arlene Alda.
