Naming Samantha's New Baby

S6, E6: Darrin's parents, Phyllis and Franks are coming to see the new baby Frank, when Endora announces that Samantha's father, Maurice, is breathing fire because the baby was not named for him. The Stephens arrive and with Endora are admiring the baby when there is a rumble, walls and furniture shake, and an irate Maurice arrives. Maurice casts a spell which gets the others out of the house while he argues with Samantha and Darrin about the name. When Darrin flatly refuses any change, Maurice puts him under a spell and freezes him into the hall mirror.
