We're in for a Bad Spell (S02E03)

When strange things begin happening to Adam Newlarkin, a friend of Darrin's, Aunt Clara tells Samantha he has inherited the spell placed by a witch on his ancestor who was a judge in Salem two hundred years before. Aunt Clara adds that unless Adam follows the antidote for the spell strictly, he will be branded a thief. The Stephens learn that Adam has been hired by a local bank. Samantha and Darrin manage to get Adam to kiss a dog, the first step. With Aunt Clara's help, Darrin dunks Adam in a pool three times. They have trouble persuading him to ride through town shouting praise of witches, which is the final step. (iTunes)
