It's really amazing what people will eat, isn't it?

Actually, I would imagine that most of them aren't too bad, if you can get over the whole idea of what you're eating. I've eaten some unusual things (tongue, kidney, escargot, squid ...) and for the most part, it's tasty, if you don't get too hung up on where it came from. On general principle, if you're a carnivore anyway, there's no real difference between eating the critter's thigh muscle and its gonads. At least, there shouldn't be. In reality, however, I think I'd have to be crawling through the desert, desperate for food, before I'd even consider the idea of eating anything's testicles ...
