All About Eva

All About Eva is the 82nd episode of Gilligan's Island and the 14th episode of the third season. It is best known as the one where Tina Louise plays two characters. It aired December 12, 1966.

Synopsis
A Plain Jane named Eva Grubb comes to the island to escape society and live by herself without being bothered. However, Gilligan and Ginger discover her boat and believe they're being rescued. However, the Professor deduced something else is up and everyone searches for Eva on the island. Gilligan discovers her, and Eva runs out to be caught by the Skipper. She surrenders the boat willingly, but the Professor reveals when they reach civilization, they'll send someone back for Eva who is distraught and shouldn't be alone. Gilligan, however, accidentally reveals this to Eva who decides to keep everyone prisoner on the island by hiding the spark plugs to her boat. Ginger decides to give Eva a makeover to buoy her spirits, but it results in Eva looking exactly like Ginger. Eva tests this similarity by coming on to Gilligan, and she returns the spark plugs. The Howells decide to throw a party to thank Eva, but Eva overhears Ginger comment that looking like her might not be enough to help her get dates. Eva secretly knocks out Ginger and tries to be her at the Howell's party by switching identities and dresses several times. The Professor soon begins to get suspicious just as Ginger returns and busts her. Eva is shocked and apologizes, but the fact that she fooled everyone during a party leaves her believing she could get away with stealing Ginger's career. She secretly leaves with the boat and leaves behind a note to the stunned Castaways and Ginger distraught and upset, never wanting to hear Eva's name ever again.

Trivia

 * The title of this episode is an homage to the Marilyn Monroe movie, "All About Eve."
 * Tina Louise gets an extra opening credit for playing Eva Grubb.
 * Gilligan mentions that they've been on the island for "years, months and days," suggesting the castaways have been on the island longer than the broadcast history of the series, but he could have just been exaggerating.
 * It is unclear in this episode if Eva legitimately resembled Ginger or just ended up looking like her after the make-over.
 * The Professor could have used psychology to let Eva know how hard it would be for her to live alone by herself on the island.
 * Gilligan and the Skipper should have just left in Eva's boat for help and left the others to talk Eva into going back with them.
 * Even if the Castaways had left Eva on the island, ownership of the boat would have been traced back to her by the authorities.
 * Mrs. Howell claims she doesn't know French, but she claims she knows it in Quick Before It Sinks.
 * Eva could have saved a lot of running by claiming as Ginger that "Eva was off exploring the other side of the island."
 * It's unrevealed as to how Eva got the keys for her boat back from the Skipper.
 * Considering how bad her eye sight was, it is debatable that Eva even made it home without her glasses.
 * The identity of the actress playing Tina Louise's body double is unrevealed.
 * It's unlikely Eva could have pulled off impersonating Ginger as her vision, hand-writing and Ginger's sister (mentioned in Hair Today, Gone Tomorrow) would have exposed her.
 * Why the Skipper or Professor didn't tamper with the boat to keep Eva from leaving without them is unrevealed.
 * This is one of the few episodes where the tag scene is left intact in syndication.

Quotes

 * Professor - "Well, I'm sorry folks, but money doesn't buy happiness!" Mrs. Howell - "Anyone who says money doesn't buy happiness doesn't know where to shop."


 * Ginger - "Well, Gilligan, what would you do if you looked like Eva?" Gilligan - "I'd go down to the draft board and get reclassified."


 * Gilligan - "Everybody, you should see Eva. Wow, what a change in her!" Skipper - "She can really turn it on, huh?" Gilligan - "I could barely turn her off!"
