Here's a neat article at Candy Addict about the top 10 urban legends about candies. For example:
The Gruesome Origins of LifeSaver's Name
Has anyone ever tried to freak you out with this little bedtime story: The inventor of LifeSavers originally designed the candies to be disks without holes, but when his poor little daughter tragically choked on one and died, he vowed to end the senseless killings, so he put holes in the middle and re-dubbed them LifeSavers? I’ve heard this one from quite a few sources, and, well, let’s think about this, people. Would that little hole prevent a kid from choking? It’d have to be lodged just right.
Naw, the real story is a lot less dramatic. In 1912, Clarence Crane began production of a peppermint candy. The machine worked best if the candies had holes in them, and he couldn’t help but compare these these donut-shaped mints with the newfangled life preservers that were becoming fashionable after the recent Titanic disaster.
