Comic actor George Furth, who later cowrote the hit Broadway musical "Company", appears in this episode as by-the-book Army captain Jonathan W. Blair. Arriving at Fort Courage, Capt. Blair chooses O'Rourke (Forrest Tucker) and Agarn (Larry Storch) in a grueling survival test. Equipped with only a knife, a couple of a canteen cups and a self-contradictory Army manual, the two troopers face a horrible demise unless O'Rourke is able to cadge a few free meals from a few unwitting sources. Showing up as an undertaker is Arthur Julian, who wrote this and several other F Troop episodes. ~ Hal Erickson, Rovi
