Heheheheheheh...
I was quite the litte bastard to the local wildlife when I was younger. I once put some firecrackers into a snakes mouth and lit them. Blew the thing into a couple of pieces. I also would shoot geese with my pellet gun and BB gun. Annoying birds they are. Also did the same thing to squirrels.
But what really takes the cake was one time me and some friends caught a bullfrog, and doused it in lighter fluid, and lit it on fire. Well, the damned thing hopped around the yard for a minute, scorching the grass, and then it somehow managed to get into the bushes in front of my friends mom's house. The thing lit the bushes on fire, and the patio that is next to the bushes. Back then it scared the crap outta us, but these days it's a story that is still good for a laugh or two.
