The 4 year old boy ran into his mother. "Mommy, Mommy, I dropped my toothbrush in the toilet!" he cried. So Mom went into the bathroom and fished it out of the toilet. "We need to throw it away because it's dirty" she said and promptly threw it in the garbage can. The little boy looked at the toothbrush in the trash, thought for a moment and said, We'd better throw yours away too. It fell in a couple of days ago!"
