It's weird that this doesn't have an option 'brains' since in some countries people really eat animals' brains. Not for me though. :P But in fact, I HAVE eaten pigs tongue lots of times. My mom used to make cooked tongue when I was smaller, and I actually liked it a lot. I would still love to eat it if it was cooked in the same way. It was delicious. :d
As for other organs, maybe cheek meat would go. And liver is pretty common meat to be used in foods, I think. Oh, actually I eat liver quite often, because there's a common finnish dish called 'maksalaatikko'.(has liver, rice and other stuff in it, usually eaten with lingonberry jam) I just forgot that it had liver in it. xD But who would eat ears..? Of course, our dog loves to eat them, but I think it would taste pretty bad. And ears don't even have any meat in them!
