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 completely off topic 
but I had to tell someone!
