Hahaha, this is really funny! The egg is a delicacy in my country as well and it's really delicious for me. It's definitely not for everyone though and it can look pretty disgusting so I guess your reaction was understandable XD
it is/was eaten here in Iceland, i personally wouldn't touch it with a ten foot pole but my father says they're tasty... but he said that about the shark too and i am still trying to forget the awful taste!
FFFFFFFFF I know that stuff. That creeps the shit out of me DDDD8 SO WRONG DO NOT WANT.
And yeah, they hold a light to it. That's a common practice, and usually required. Most often to find if there is blood in the egg before it ships :3 Though it takes something a bit more high powered than a flashlight though. a regular light bulb does it though. I've done it before on a farm I went to summer camp as a kid. it's really interesting, but at the same time, really creep D:!
