The list of seafish being cooked alive, Kobe beef that lives a life comparable to a prince (before slaughter) or a fish so poisonous that only the chef that has been trained for 2 years is Endless. but even veg foods are really Weird. I am only listed ones that are considered as a delicacy in the developed world. If I add the African/tribal culture then the list is endless.

I have known children who can go on and on about the Hotlix candy with a scorpion inside or Beanboozled vomit flavored jelly beans. Maybe these items are marked as delicacies and not food items that expired last yeear because each and every one comes with a unique story. I guess it is true: Men never group up. They are the same old weird boys but now with money to burn.
