My grandpa talked me into trying dogfish when I was a kid. There was a pretty decent strip of meat that he'd take from the tail, up to about the first fin. I don't think he did anything special - just fried it up. I never died, and didn't think it was that bad. No bones to worry about (all cartilige). Just don't use your good knife, the skin is very tough and like sand paper.
He also had us eating sculpin (bullheads), moonsnails, and other weird stuff.
