If you were going to OFF YOURSELF?

.....how would you do it. Imagine, for example, that someone is holding a puppy hostage and you have to take your own life or the pooch gets it, how do you go about it? Personally, I think I'd want to go skydiving sans-chute. It would be a rush and also a truly awe-inspiring experience to fall through huge ulonimbus clouds at 20,000 ft..
