The next time you are chided for bad behavior, blame it on the whole apple, pear or pretty much any uncut food that your parents packed in your lunch box. That's because biting into anything that requires the use of the front teeth, is likely to cause rowdy behavior in kids!

While some were kept for lab tests most, were returned to their original locations....
