A friend of mine told me about a kid in his class who had a pet slug. Apparently, one day the class happened to be discussing how salt kills slugs when you put it on them. This kid said, "Wait, salt KILLS slugs?!?" The poor kid's uncle had put salt on the pet slug and then told the kid that the slug was now "hibernating". The kid believed him... until he heard this. Which (this is disgusting) was a year after his uncle had put salt on the slug!!!
