It's an antique

The mooore you knooooooooow

But was it his milk??

Well when he became king, William Blount wrote that "The heavens laugh, the earth exults, all things are full of milk, of honey, of nectar. So it can be concluded that there was some milk around, and maybe it was his. I don't know about this plastic, though. Maybe it changed containers.

Warm milk was a hangover cure at the time. That much I know.
