April 9, 1940 a Dish Best Served Cold

Interesting. In the US at least Crotons are rather popular as houseplants. I've kept them for years, and never knew of this property or story.

Assuming it's true, I wonder if any documentation exists at all from one of the affected souls on those subs.

Sounds cool. Also sounds like something the Kriegsmarine could trace back up their supply chain. Which the Resistance would know. What was their plan for that, and how did things work out?

Another Historical Easter Egg from Wikipedia [1]:

"Medicinal" croton oil was supplied in the California Genocide to dying Indian groups.
