Americans and I'm assuming most Europeans, have a natural dislike of worms. They're creepy, sometimes slimy, and they move in what seems an unnatural and distasteful way. I remember going fishing when I was a kid and putting the red earth worm on my hook. As soon as the sharp end of the hook would penetrate the worm's flesh it would wiggle vigorously and inevitably turn its head toward my hand as if it were trying to bite me. I knew even then that earth worms didn't bite, but I still hated the odd little way the worm moved.
