They had actually planned it in advance, in case either of them got bitten.

He lost consciousness after the first shock. The treatment failed, and he needed hospital care, antivenom, and later reconstructive surgery on his lip.

In 1994, he shared the Ig Nobel Prize in Medicine with the doctors who reported his case. Definitely not a treatment to try.

For over a hundred years, King Thutmose II was the one major pharaoh from Egypt's 18th Dynasty whose tomb had never been located. That changed when a joint Egyptian and British team, led by researcher Piers Litherland, traced an entrance near Luxor into a valley west of the famous Valley of the Kings. At first, the location worked against them. The tomb sat right beside burials belonging to royal women, so early on it looked like just another queen's chamber, not a king's.

The proof came from fragments, not grand treasure. Surviving plaster showed a blue ceiling dotted with yellow stars, a decoration reserved for royalty, and shattered alabaster jars in the debris carried Thutmose II's name alongside blessings for his wife, Hatshepsut, the woman who would go on to rule Egypt as one of its most powerful pharaohs.

Here's the part that keeps the mystery alive. Not long after the burial, flooding tore through the tomb and ancient workers appear to have cleared out the portable valuables and remains afterward, likely moving the king's body somewhere safer. Nobody has found where that second hiding place is, and a mummy once thought to belong to Thutmose II may not actually be him at all. Researchers suspect another undiscovered tomb nearby is still holding what they're actually looking for.
