Today, I went to the beach with my kids. 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 totally off topic but I had to tell someone!
