I also agree with cache 22, when I as a kid I carried a spreading adder around in my pocket...just kick a little dirt on a spreading adder and it will play dead, roll on to its back with its mouth open and tongue hanging out...looks really dead until you roll it back over on its belly, then it rolls back on its back and plays dead again...cannot make one bite you (I couldn't anyway)...I stopped carrying it around in my pocket when my Grandma asked what was moving in my pocket...she was sweeping out the well house and broke out the light fixture when she tried to hit the snake and me with the broom...from that day on she thought I was a troubled child...never could catch a blue racer...
Save the planet, it is my favorite place to fish...
