When I was about 12, a friend bought me a big knife back from holiday as a present.
So we went outside to chop some things up with it. As I was hacking away at some wood, I hit my finger with the blade right on the joint and it went right in.
We both examined the wound which was only bleeding slightly. We could see veins and bones, it was *very* interesting. Then one of the veins burst and it started spraying blood out in a pleasing arc, IN TIME WITH MY HEART BEAT!
We both agreed it was one of the coolest things we'd ever seen.
It's around this point that things started to go wrong. I tried to make the bleeding go away (failed), so I put a big plaster round it. Which fell off soaked in blood after about 2 seconds. So I grabbed my mums best tea towel off the line and wrapped that round it. That too was soaked in a few seconds.
Hmmm, we were going to miss Thunderbirds at this rate so my mate suggested putting my hand in a bin bag. The bleeding would stop eventually and I'd stop leaving this sticky red stuff everywhere. Brilliant!
Top tip.
A child can watch most of an episode of Thunderbirds while bleeding profusely from his finger before passing out.
