The House That Uncle Arthur Built (S07E18)

Uncle Arthur is in love – hopelessly in love – with Aretha, a snob-bish witch who can't and won't tolerate a practical joker. Attempting to conceal the fact that he is an uncontrollable "jokoholic," Uncle Arthur casts a spell which transfers all his pranks to the Stephens' home – literally turning it into a fun house.
