Samantha's Thanksgiving to Remember

To get into the Thanksgiving spirit, Aunt Clara zaps the Stephens and Gladys, who just happened to be nosing around, to seventeenth century Salem. Darrin lights a fire with a out-of-place match and is charged for witchery. Samantha then defends him at the trial and Darrin is cleared. Then Aunt Clara brings them back and Gladys runs off to tell Abner about her fantastic trip, but at soon as she reaches her door, Samantha changes her costume.
