  3. Today, I went to the beach with my children. I found a sea shell and gave it to my 4 year
    old daughter and said "You can hear the ocean if you put this to your ear."
    She placed the shell to her ear and screamed.
    There was a hermit crab inside and it pinched her ear.

    She never wants to go back! LoL I know this is
