What Ridiculous Things Did Your Parents Tell You?

Most of us believed everything our parents told us when we were little. I remember sitting at the dinner table, choking down every last carrot on my plate because my Grandfather had told me, "if you don't eat your carrots you'll go blind".

I know I have told my kids things that aren't 100% true. Just the other day I told my son that if he ever mooned anyone he would go to jail FOREVER. Other things our parents told us or we have told our children are:

• If you swallow gum it stays in your stomach forever.
• If eat watermelon seeds, a watermelon will grow in your belly.
• If you pee in the pool the water will turn green.

What ridiculous things did your parents tell you when you were growing up? Do you say ridiculous things to your children that aren't 100% true?
