Who’s going to clean up the mess?
Well, if it *has* to have cultural roots, then I suppose Louisiana would be the place to construct a 21st-century guillotine. Get the prisoners at Angola to help out with the project.
Coat all the metal with an industrial non-stick surface and build in a car wash-like rinsing system. Maybe even add an oversized skeeball rig to catch the heads.
I like that idea. I'm thinking a little drop through an oversized Pachinko machine. Prizes for anyone betting on the hole it ends up in.
OTOH, the thing was used in the 20th century, and not by the French, but the Nazis. Very efficient. Not the best advertisement, though.
