My mom was a surgical RN. She retired in 1985, so right in the middle of the St. Elsewhere run. My mom told some pretty wild stories about what happened at the hospital, especially during the 9 years she worked graveyard shift in the OR, which often including covering in the ER in quiet times. Some of the practical jokes they played were great.
St. Elsewhere launched a lot of careers. Loved Denzel Washington, but have to admit I have not seen a single one of his movies, to me he is still Dr. Chandler. Howie Mandel has done well. Doris Roberts and James Coco were great guest stars.
