"Not Guilty" is an intriguing episode that indulges in hilarious byplay in an unusual whodunit setting. This time Gilligan reels in a crate full of newspapers featuring blaring headlines announcing that all seven passengers aboard the SS Minnow are wanted for questioning in the murder of Randolph Blake. The first person that the Skipper and Gilligan visit is the Professor, just as he delightedly demonstrates a new ready made guillotine! They find Ginger and Mary Ann in the process of boiling poison, supposedly to kill the mice around the huts. The Skipper initially scoffs at Gilligan's attempt to barricade the door against intruders, until he's reminded that until they were shipwrecked they 'didn't know any of these people!' Suspicion grows among all seven, but credibility is stretched when Mr. Howell, the Professor, and both Ginger and Mary Ann all claim to have known the murder victim, who turns out to have been a real scoundrel. The denouement is the only one possible, with poor Gilligan in the role of Randolph Blake in a Perry Mason-style reenactment of the crime.
