Weird Food I Have Eaten

So, while Im down here in Brazil, Ive decided to have an open mind about the food I eat. My first encounter with strange food, however, occurred by accident. In Brazil they have restaurants where the charge you per kilo of food you get and it is like a buffet, so one time we went to this per kilo restaurant and I loaded up on some rice and beans and meat, and I didnt look at the sign that said what type of meat I was getting, it wasn't until I finished eating it that my sister decided to tell me it was tongue, so that was a nice surprise, never would have eaten that if I had known what it was, but alas I ate it, and it wasnt so bad. All the other things I have tried have been willingly and knowingly. While in Floripa we went to many churrascas (BBQ's) and one of their favorite things to cook up is chicken hearts, they put about 8 per skewer and grill em up and chow down and tons of chicken hearts, so Ive been trying them each time, and they are tasty, but the idea still kinda freaks me out. Also we had chicken cooked in its own blood, with a lovely blood sauce on it, which again was actually pretty tasty. And while we didn't end up eating this, on Thanksgiving we tried to buy a whole chicken and cook it up, only to realize after we bought it that is still had all its insides AND its head and feet still attached, which was a pleasant surprise, so we just ended up throwing it out and getting some chicken breast instead. Anyways, those are the weirdest things I have eaten so far!
