There’s an extremely violent and depressing novel that used to be required reading in the 6th grade called Where the Red Fern Grows. It was a story about a boy and his two 'coon hounds. Somewhere in it is described the following method for catching a racoon:
Drill a 1/2 inch hole in a barrell or box. Place a coin or other shiny object just inside the hole. A racoon will come along and grab the object, but will be unable to remove its hand (paw?) without letting go of the object. Apparently, racoons are so greedy that they will never let go. All the enterprising young trapper has to do then is brain the dumb creature with a 2x4.
Does this actually work or is it just the twisted invention of a writer of violent and depressing children’s books?
