When I was little I remember being told that if a turtle bites you it will not let go until it thunders.
I found this to be untrue when my young son was bitten by a turtle. We put antibiotic ointment on the bite and from that day until this we still call it “turtle bite cream”.
Haha, that reminds of the time as a boy that I held a pet box turtle up to my brother for him to say “goodbye” to it before we headed to church: My brother leaned in a little too close and the turtle chomped onto my brother’s nose! I don’t remember exactly how we got it to let go, but my Mom says it did hang on for a little while.
