my beloved grandfather used to eat the grossest things...lol. he ate brains and eggs, poke salad (or "poke salit", as he called it, it's really just a weed...lol) and eggs, pickled pig feet, those really gross looking eggs you see in big jars on the counters at convenience stores, you name it, he'd eat it.
i will absolutely NEVER, EVER, eat any of these things. i also refuse to eat sardines, salmon, boiled cabbage, fettuccine alfredo, or cottage cheese. with the first 4, it's the smell that gets me. with the cottage cheese...i can't get over how it looks.
