On another note, lots of people eat eyeballs and tuna eye is considered a rare delicacy. This is a pretty boring way of making it but I would eat eyeballs if they were made nicely.
I was in Australia years ago visiting family and ordered the shrimp; didn't know it was the whole shrimp, eyes and all. And these were big shrimp! I was a little grossed out but I didn't want to be rude so I ate them. Shortly after that I became a vegetarian tho.. :/
