Another favourite of mine: Hary Blank, Denture Therapist.

Ok,

Doctor Pus - Orthodontia - Kitchener, ON!

Dr. Kevin De Cock of the World Health Organization - circumcision advocate

Dr. Stubbs and Dr. Long - Cosmetic phalloplasty (penis-lengthening technique)

Had some other good ones, but forgot them! I need to carry a book with me at all times!
