I was on Renaissance Island, Aruba, in a lounge chair, eating a hamburger, when a passing iguana leaped onto my chest and took a bite out of my hamburger. I grabbed it with both hands and threw it off of me. I then led it down the beach holding out the rest of my hamburger until it was too far down the beach to jump me again !!! True story. My hands bled just a bit from it tough skin. True story !!!
