Raw deer liver. It is a local custom to eat a big bite of the raw liver of the first deer you ever harvest while hunting. It wasn't near as bad as I had imagined but I wouldn't want to make a steady diet of it. Somebody told me that deer had liver flukes, some kind of parasite, but the vet told me they were harmless to humans.
As kids in school we use to swallow BBs, the copper coated ones and they would come out shiney and bright just like they went down! Lucky not to get lead posioning.
One junebug by accident while motorcycling. Either had to swallow or choke. Had no flavor at all.
My inlaws cooking which was pretty disgusting after being use to eating spicy food all my life. No salt or pepper or anything. Tasted a lot like that junebug! No flavor at all!
Habenaro pepper relish. Tasted like a blow torch!
European beer at room temperature when I was in the service. It was all I could do to down about 12 pints. Caused me to throw up and speak in tongues. Almost a religious experience! Monty
