Remember the episode about Anthony...the little boy who didn't want anyone around him who thought BAD Thoughts and would dispatch the bad thought folks to a cornfield we never saw from which they never returned again?
I bet dementia don would fit right in with all of them don't you? Who else but Rod Serling could figger out a way to get don gone to that exact place? A bloodless coup.
After all dementia don only thinks bad thoughts which is why he do do the bad deeds he do do. SIGH.
