Dr. Chinstrap

Dr. Chinstrap was a psychiatrist who was an expert in the mental illness of hoarding. Wendy sought out his help to get Stan to deal with his own hoarding. In the course of his investigations, Chinstrap also discovered that Mr. Mackey was a hoarder, and attempted to hypnotize the two (along with a luckless shepherd) to regress to their childhoods to discover what caused their habit of hoarding.
