I like fish.

Blow fish:
a poisonous chemical called tetrodoxin found in its skin, blood, ovaries and especially its liver. This is a toxin that makes cyanide look like Aspirin - one match-head worth can kill thousands. Just touching a fugu the wrong way can be deadly and, appropriately, our multi-course feast started with a salad made with the skin.

Most reports of fatal fugu poisoning concern fishermen who, having had the fortune to catch a fugu, lacked the foresight to throw it back. They attempt to "sashimi" the fish themselves and pay the ultimate price. Not, however, before experiencing a numbing of the lips and tongue, a growing paralysis of the body, headaches, gastric pain, vomiting and convulsions. It's not all bad though, you do get the consolation of a light and floaty feeling. After 4-6 hours of this, death occurs. There is no known antidote.

The should have saved it until the end of the meal.  That way, while you are dying, you will have something to spew.
