2. ST. ELSEWHERE
(1982-1988)
The finale showed us the autistic son of hero Dr. Westphall (Ed Flanders) playing with a snow globe, lost in thought. The camera moves in closer, and we see it contains a replica of the hospital show's St. Eligius building. It was therefore assumed that all six seasons of St. Elsewhere took place in the son's imagination. Mind-blower! Ken Tucker
