As a kid I remember the horror on my mom's face when she saw me put two pennies in my mouth to suck on. "Take those out of your mouth! You have no idea where they have been!" were her sage words. The panic in her voice worked its magic and I promptly spit them out. Little did she know that in addition to the gross possibilities of where they had been, had I swallowed them I could have been in trouble for other reasons.
