 The scene with the radio report is one of two scenes that reveal the names of the Skipper (Jonas Grumby) and the Professor (Roy Hinkley); the names are used in a similar radio report early in the series.The name Jonas Grumby appears nowhere else in the series except for an episode in which the Maritime Board of Review blames the Skipper for the loss of the "Minnow".The name Roy Hinkley is used one other time when Mr. Howell introduces the Professor as Roy Huntley and the professor corrects him, to which Mr. Howell replies, "Brinkley, Brinkley."
