Okay, Who's the Wise Witch?

Samantha and Darrin find they cannot leave the house. Doors are locked and windows unbreakable.

An amusing episode, interesting due to the fact all the regulars and two frequent guest characters (Esmeralda and Dr. Bombay) appear. Witches can pop in but cannot pop out of the house. Esmeralda comes in with a mudpack on, saying she has a date. Endora asks her if it's Cary Grant, Darrin says "Ulysses S. Grant?" Bombay shows up in a matador costume.
