I was reading something in Wikipedia about the fountain of youth while looking for some good names for a pharma data warehouse. This fact entertained me since I've always found it funny that a movie was made out of a ride at Disneyworld. It all connects back in the movie though here...

" The 2007 film Pirates of the Caribbean: At World's End ends with Captain Jack Sparrow heading off to find the Fountain of Youth, positioned in southern Florida (Disney World, to be exact) according to his map."
