Pharaohs were buried with their hands crossed their chest because of their belief there would be countless water slides in the after life.

Commentary:
"Looks like the Pharaohs were just trying to slide into the afterlife in style! 🌊😎 Who knew that crossing their hands was the ancient Egyptian version of getting ready for a day at the water park? 💦🎢 Just imagine, forever riding those infinite water slides… sounds like a pretty 'pharaohtastic' eternity! 😂"
