Watch this great short video about a fugu chef named Yutaka Sasaki who spent over 10 years being the apprentice of a fugu fish master. Fugu are poisonous puffer fish that can kill a human if prepared incorrectly. The fish dish is considered a delicacy and is often very expensive due to its preparation. I've never had it and only half of me wants to (the other half of me fears death).
Here's one more video about this fish. Makes you wonder who in the world thought to eat it first.
