t's Darrin's birthday. Maurice, who has come to appreciate Darrin if only because he makes Samantha happy, comes by for an unexpected visit to wish Darrin a happy birthday and to give him a birthday present: a perpetual calendar that allows Darrin to have powers of witchcraft. After Darrin declines the gift, an incensed Maurice accuses Darrin figuratively of being a jackass. So Maurice literally turns Darrin into a jackass. Beyond the issue of Samantha trying to get her father to turn Darrin back into a human, other problems arise in the forms of nosy Gladys Kravitz, who sees the jackass and does what she believes is her neighborhood and public duty to get rid of it, and Maurice himself, who may not be able to reverse the spell as easy as it was to perform the spell in the first place.
