The Leprechaun

S2 E27: Darrin reacts violently when he finds Brian O'Brian, a sprightly leprechaun, a guest in his home. Samantha tells him that Brian is not her relative but the leprechaun of Darrin's family. Brian reveals he has come to recover his pot of gold which was hidden in a fireplace brought to America by James Dennis Robinson. Darrin finds that Robinson owns a company whose account would be a great asset to Darrin's agency. Brian breaks into Robinson's house to retrieve the gold and is arrested. Darrin allows Samantha to use her magic to get Brian out of jail. Brian pleads with Samantha to help him recover his pot of gold which will restore his lost powers.
