Doctor in the House

It's All in the Mind (9x7)

:

An attractive young lady out-patient asks Dick and Duncan to her fancy dress party, where her 'costume' will be Lady Godiva. Duncan plans to go as a witch-doctor but Griffin, who has been reading a book on head-hunters of Borneo, mishears him ordering his costume and assumes that a witch-doctor is working in the hospital. He tells Beaumont, who believes he is over-doing it and sends him home, asking Duncan to replace him. Arriving in costume Duncan frightens the out-patients.
