El Día De Los Muertos may be a Mexican holiday that traces back to the Aztecs, but Disney would like to give the silent treatment to those 2,000-3,000 years of cultural tradition and co-opt the phrase for its own greedy gringo purposes: On May 1, Disney filed 10 applications for various trademarks relating to the phrase "Día De Los Muertos." And, hey, why not—the Aztecs never bothered to trademark it.
