John Morgan

 is Councilman Green's campaign manager. He and Green respond to Gladys Kravitz's call to investigate the strange things happening at the Stephens' house on Halloween night.

The strange things happen to be Endora's Halloween party. Uncle Arthur runs interference so that Morgan and Green pass from the front of the house to the back without ever setting foot in the house. Bewildered by their experience, Green promises not to say anything if Morgan does not.
