Now I can't get that scene from One Flew Over the Cuckoo's Nest out of my mind.
Enough inmates break out to fill a bus, so they steal an Asylum bus.
They want to rent a boat (? I think that was it?) but Jack knows no one would rent to a bunch of escaped mental inmates.
So he introduced the boat owner to "Doctor This" and "Professor That".
Boy, as SOON as you put "Doctor" in front of their names, their symptoms and tics started to look like eccentricities.
Yes, therapy. Need it, got it right here, never goin' anywhere else.
