In the United States, and in some other countries, no doctor wants to be called “a quack“. (An entire web site called Quackwatch devotes itself to reporting on doctors who are, in the view of Quackwatch, quacks.)
Doctors who fear being called “a quack” can but envy No Kwak, MD. Everyone can happily agree that this physician is No Kwak.
Dr. No Kwak is affiliated with Glen Cove Hospital, with Huntington Hospital, with Lenox Hill Hospital, with Long Island Jewish Forest Hills, with Long Island Jewish Medical Center, with Long Island Jewish Valley Stream, with North Shore University Hospital, with Plainview Hospital, with Southside Hospital, and with Syosset Hospital. So far as we have determined, Dr. No Kwak is the only physician whom each and every one of those institutions has ever specifically said is No Kwak.
(Thanks to Ivan Oransky, who has often brought quacks to our attention, for bringing No Kwak to our attention.)
