A cow-orker picked up a bag of some chip-like snack containing Olestra, read the above warning on it, ate the entire bag in one sitting anyway and shit like a goose for a couple days - an early forerunner of the modern FAFO.
You can trick people into eating half a pound of Escolar (an oily fish with a buttery texture) and get even more explosive results. It would be disastrous to combine Escolar with Wow! potato chips.
The main health concern with eating escolar is keriorrhea, a type of oily diarrhea caused by indigestible wax esters in the fish, leading to symptoms like abdominal cramps, nausea, headaches, and oily, yellow/orange discharge, often occurring a few hours after eating, though it's generally not severe and resolves within 24-48 hours. Escolar is also frequently mislabeled as "white tuna" or other fish, adding a layer of risk, and is banned in some countries like Italy and Japan due to these digestive issues.
