Dr. Foster is Ned Flanders' childhood psychologist with whom he underwent anger management therapy so as never to lose his temper. Flanders once snapped, letting out all his anger, resulting in a reunion between Foster and Flanders. His name may come from a famous nursery rhyme "Dr Foster went to Gloucester".
 University of Minnesota
Dr. Foster worked on a break through therapy at the University of Minnesota. The child anger management therapy was known as the University of Minnesota's Spankological Protocol. The therapy entailed 8 months of non-stop spanking. At the end of the period, Ned was asked a number of questions which he normally would have replied to in an angry manner. According to Foster, the therapy worked so well that Flanders repressed all anger. Ned substituted anger with the nonsensical jibberish he is known for using as an adult.
