My parents told the following:
Carrots would give you nightvision.
Brussel sprouts would make you smarter.
Raw cookie dough gave you worms.
Biting your fingernails made bugs appear and live in your stomach.
If you swallowed gum, it would be in your stomach for 7 years.
If your cracked your knuckles, they would grow out deformed.
Ladybugs were poisionious.
If you swallowed a penny, the US Mint would hunt you down and cut it out of you.
If your feet come out of bed (after I was put to bed), the devil's hands will reach up out of the ground and pull you down to hell.
My Dad was the one in charge of turning the sun on and off.
Whenever my Dad would pass gas, he'd ask if I'd seen that elephant run by. I finally got tired of that one and told him he needed to just say he farted...he wasn't too pleased with me.
There was a man living in our lightbulbs that turned them on and off, and he'd come after me if I left any lights on in a room I wasn't in.
Spiders tap danced at night on my toothbrush if I didn't brush my teeth. Don't ask me what in the WORLD possessed my parents to tell me that one. I always brushed them 3 times a day, for feet of having "spider legs" in my toothbrush.
