Wow, I'd like to try a bear steak. I just read "The Rise of Theodore Roosevelt" and he loved 'em - of course he shot his own bear too. Great book, read it!
Natto doesn't bother me much, probably because I grew up eating, and am still never without, Vegemite for breakfast. The only horrible part is that it's so sticky, if you get any on your lips it's going to be there all day.
I once worked with a guy in Japan who wanted to see me refuse to eat something. He was disappointed when I ate sushi, even more so when I ate natto, but he had one final try. We went to a pub in Tokyo where there was a fishtank by the entrance full of silver fish about 10" long. He pointed at them and giggled horribly, then we sat down and he ordered. One of the fish came out as whole sashimi, impaled on a skewer curved with its tail in the air. He offered it to me giggling like a torturer who loves his work and when I took a piece it twitched - still alive. I ate it, and he got over his disappointment by poking the fish some more.
