Take one (1) living monkey. The story does not work without the kicking and the screaming and the biting. Just eating monkey brain stew is not particularly interesting or shocking.
Strap beneath special table with hole in center. The monkey must be strapped beneath a table with its head poking up through a hole.
Bop monkey on the head, scoop and serve. The diners usually deliver the fatal blow themselves with hammers, the skull is sawed off and the brains are scooped out with spoons.
