I've always wanted to try fugu though. I know some people who've eaten it and apparently the "safe" cuts of the fish carry a trace of tetrodotoxin which makes your tongue tingle. I also heard that in the aftermath of WWII, a lot of Japanese people were dying from eating poorly prepared fugu, so General MacArthur created a law requiring training and certification for all fugu chefs.
