Lord Edmund Blackadder (Rowan Atkinson) seethes with jealousy when Sir Walter Raleigh, freshly returned from the New World, presents Queen Elizabeth (Miranda Richardson) with a potato. Vowing that anything Sir Walter can do, he can do better, Edmund sets out on an exploring expedition of his own. Alas and alack, he secures the services of England's least reliable mariner, Captain Redbeard Rum (Tom Baker). "Potato" was first telecast on January 23, 1986. ~ Hal Erickson, Rovi
