Mr. Potter

 (John Paul Potter III) is a drunk who roams the streets of Gloucester and Salem, Massachusetts.

Mr. Potter witnesses some strange events he attributes to witches. In Salem, he sees Endora change the ugly witch tourism signs to signs with a beautiful witch. He sees a bedwarmer levitate and whack Darrin over the head. He sees Samantha appear and disappear in the jail cell he shares with Darrin.

In Gloucester, he sees Samantha and Serena popping in and out of the Gloucester House restaurant where he is getting sauced at the bar.

He tells anyone who will listen about the astounding things he has seen, but the police disbelieve him, attributing it to drunken hallucinations.
