What's something you've eaten that grosses out others?

Whenever DH and I go out to eat with the in-laws, we always eat at Turkish or Russian restaurants. (they're from Russia)

They always try to get me to eat things I don't want to eat. It's like a game with them. They order in Russian so I don't know what it is and then try to get me to try it before they tell me.

That's how I wound up eating pate once and beef tongue another time. I actually like them, if you can believe it.

But I still refuse to eat fish. And they still ask me why. Every. Single. Time.
