Forrest Tucker plays a dual role in this episode as both Sgt. O'Rourke and O'Rourke's Irish-born father. Arriving in Fort Courage fresh from the Emerald Isle, the bombastic elder O'Rourke quickly sets abuout transforming the fort into an American replica of the Auld Sod. When it becomes obvious that O'Rourke Sr. has no intention of returning home, Cpl. Agarn (Larry Storch) must persuade him to do so--by disguising himself as a leprechaun! ~ Hal Erickson, Rovi
