Some applications of technology are just ... strange. That being said, I think there's something beautiful about science being done "just to see if we can".
Not every experiment needs to be in pursuit of some grand truth or miracle cure... Sometimes it's nice just to be curious.
In that regard, the researchers who recreated a 3,000-Year-Old Egyptian mummy's voice might "take the cake" (or "drop the mic").

The mummy's name is Nesyamun. They used a 3D printer and an electronic larynx to create the sound. They didn't recreate his tongue - so his voice doesn't take that into account. From what I can tell, all they've gotten "him" to say is "ehh". Very mummy-like.
For what it's worth, they did test this methodology on a living human to validate it before going to some 3000-year-old dead guy.
Here's an interview with one of the scientists on BBC's Inside Science.
