I had a pet rabbit while I was a kid. I got bored with it and my mom would feed it.

So with some freinds, who were about as sick as I was, we took an M80 fire cracker and, while my buddy held the rabbit upside down, I tried to force the bomb up the struggling rodents ass. It didnt work at first, so we got my dads motor oild from the garage. By now the rabbit was traumatized from the attempted anal rape.

We chickened out in the end, but it was a sick thing to do. My mom gave the rabbit away to someone who actually cared about it.

I regret that.
