Ha ha...
Mind you, I help out with a kids group for my local Wildlife Trust, and in the last year I have embedded a large piece or reed in my thumb, hit myself in the other thumb with an axe (whilst demonstrating how to use an axe safely), had the entire group of kids charged by a cow defending its calf, and caused an explosion when firelighting (blew myself and one of the kids up).
I'm told by the Trust manager that I'm now mentioned by name on their insurance.
