When I hear of an opportunity to try a new food, I do. I've eaten rat, snake, alligator, kangaroo, snail, assorted bugs (ants, cockroach, crickets, grasshoppers, spiders, worms, grubs; most fried, some raw), liver, tongue, heart of various animals, every kind of edible plant imaginable, roadkill turkey (had a crazy neighbor who found out I was just as crazy that thanksgiving), possum, oyster, eggs (ostrich, emu, salmon, some other fish), chicken feet, pig feet and finally sheep placenta, to name a few of the more mentionable ones. The rat had burned hair around the legs and head and was on a wooden stick. The worms were when I was a kid and liked eating stuff I'd find outside. The sheep placenta was well prepared and presented but frankly gross. Escargot I tried because of Earthbound and found the texture a bit revolting. I'm apparently allergic to oysters, but tried one recently. Equally revolting texture. For some reason octopus tentacles aren't bad fried despite a similar texture.
I've avoided brain because I heard of a viral protein disease you can catch from even cooked brains. Dunno if that's a legend or what.
