The Petries are surprised when Harrison B. Harding (Allan Melvin), who says he's an old friend of Rob's, drops in for a visit. No one is more surprised than Rob, who has no recollection of Harding whatsoever. A subsequent series of curious events, capped by the disappearance of Rob's watch, convinces our hero that Mr. Harrison B. Harding is actually a con artist and a thief! This episode was originally telecast as a special on Monday evening, November 6, 1962, right after a Danny Kaye special, as a ploy to boost the ratings of The Dick Van Dyke Show, which was then languishing in a little-watched Tuesday night time slot. (Trivia note: According to TV Guide, the episode originally scheduled to air on November 6 was "To Tell or Not to Tell," which wasn't seen until November 14.)
