It's clever, but we have so many questions.

For a variety of reasons, October 31, 2020 is going to be a very strange day on the calendar. More specifically, it marks the first time in 76 years that a blue moon (the second full moon in a calendar month) has occurred on Halloween. Given how strange and scary this year has been already, it's a fitting occurrence to say the least. 

While there are a lot of restaurants doing Halloween deals for customers in costume or other special offerings, Denny's has decided to specifically lean into the "blue moon" angle to create a limited-edition cursed sandwich to mark the occasion. 

This October 31, Denny's is taking the title of their Moons Over My Hammy breakfast sandwich rather literally, changing its name to the Blue Moons Over My Hammy for one day only at just 20 Denny's locations in the greater Miami-Dade area. Its ingredients are functionally the same, meaning you'll still find ham, scramble eggs, and a blend of Swiss and American cheese between two slices of sourdough bread.

The difference, though, is that Denny's will somehow be using blue sourdough bread to serve this sandwich. The end result is something deeply unsettling, because there's no way that bread should ever be blue unless something has gone very, very wrong. 

For their part, Denny's doesn't seem too concerned that Miami diners might think they're being served a breakfast sandwich between two slices of pure mold. 

"With Halloween looking very different this year, we took the opportunity to make our world famous sandwich look different as well," said Denny's chief brand officer John Dillon in a press release. "This colorful upgrade gave us an opportunity to have some fun and show our guests that anything is possible in 2020!"

To paraphrase Jeff Goldbum's famous line from Jurassic Park, Denny's was so preoccupied with whether or not they could make blue sourdough bread that they didn't stop to think about whether or not they should.

For better or worse, the good news is that you'll only encounter the Blue Moons Over My Hammy in the Miami area while supplies last. Whether that means they'll disappear quickly or just kind of creepily linger around forever remains to be seen.
