These days, if a stuffed animal's plastic eye so much as wiggles, that toy is recalled faster than you can say "class action lawsuit." Back in the day, though, child safety consisted of just getting out of the way and letting natural selection do its thing. If a kid was too dumb to play with a toy the right way, well, he'd just have to learn to get along with one less eye.

That meant molten glass, molten metal, hazardous chemicals -- all were included in toys back then ... on purpose.
