I have eaten many things that others consider to be disgusting; but I have an excuse, in my life BC (before children) I was a chef. While in culinary school we had to try all sorts of "exotic" foods from around the world. *shudder*
What stands out as the WORST though comes from my childhood. Pickled Herring.

Oh my fuck, just
saying the words makes my mouth water in that "not so good" way. My Da LOVES the stuff. He'd buy it in a jar from the grocery store and just eat it straight...
Oh, I don't feel so good now.
