By my own standards, I haven't really eaten much of anything I consider strange, but I'm used to eating a variety of multicultural foods and am especially familiar with certain ones people have stated as being weird as I've basically grown up with some of those foods. A few of those foods I've grown up being used to that I'll bet some people on here would find unusual are beef tongues, lamb brains, and lamb testicles.
Also, I'm not quite sure about this one, but are chicken hearts and gizzards considered strange to any of you? I don't know what those are considered to be. Regardless, I eat them, too.
