I am sure when people first saw the episode title, they most likely thought an actual hand that was dead.

The clue was ambiguous either way I guess. GM1 had a very good guess because the episode title for "Lost Fountain of Youth" mentions nothing of a Water Bottle. That even threw my off the first time when I was looking for the episode summary in the King's Storeroom. Throughout the whole episode even Olmec refers to the artifact as the Water Bottle. I don't know why they just didn't name it "The Lost Water Bottle of Ponce de Leon).
