Henry Jones guest stars as Brian O'Brien, a leprechaun who has lost his pot of gold. Hoping to snap Brian out of his doldrums, Samantha embarks on a search for the missing pot. It turns out that the elusive gold is in the possession of one James Dennis Robinson (Parley Baer), who, as luck would have it, is Darrin's newest client. Written by those darlin' lads Paul David and John L. Greene, "The Leprechaun" was first telecast on March 17, 1966 (Saint Paddy's day, don't ya know).
