Not that it makes much difference, but I seriously doubt his candy was full of maggots and spiderwebs. It was probably weevils, those little creepy-crawlies that invade your flour when it's been around too long. They were more than likely in the nuts that were used to make the candy.
That actually happened to me when I was in high school. I bought a Payday bar at the local Walgreens, opened it up, and it was squirming. I was so freaked out I dropped it in the nearest thrash-can, didn't even return it.
To this day I don't eat anything without looking it over first.
