I got violently ill eating fish once and have had a hard time eating it since. There is about a 50-50 chance I will be puking my guts out .. so I pretty much abstain. That said, I do like shark. Back when the tuna fleet used to be in San Diego, my Mom was the accountant at a boating company and would bring home sharks, swordfish, etc all the time.
Once, she came home with a huge shark, we were going to have people over the next day for a cookout. We wrapped the shark in saran wrap (used about 3 or 4 large rolls of the stuff) and left it in the pool overnight, then a guy came over the next day to turn it into steaks. I kept the jaw with teeth for several years.
