Dr. Morton

Dr. Morton is a psychiatrist in a coma dream Bart had.

History
In Bart's coma dream, when he started seeing ghosts of dead people, Milhouse suggested he go see Dr. Samuel Elkins. When Bart found out that Dr. Elkins was dead, Dr. Elkins asked Bart to get revenge on Dr. Morton for him, as Dr. Morton wouldn't shut up about his. Bart then used the same maze prank on Dr. Morton that he used on Lisa, causing Morton to get scared. Dr. Elkins then thanked Bart and moved on to Hell.
