I've been pretty lucky so far (touch wood)! For me, the worst pain I can remember is when I was about 9 or 10, and I was living on a dairy farm. We used to burn our household rubbish in a big steel drum in the middle of the house paddock. I took over the plastic rubbish bin from the house, and emptied it into the drum. For some reason, however, the drum was already pretty full, so the rubbish ended up overflowing onto the ground. Fun! I set fire to the rubbish in the drum AND on the ground, and had a good time watching things get incinerated.
After a while, I decided to go back to the house, so I picked up the plastic house bin and started walking back. Now, I was not the most observant, and I missed that the bottom half of the house bin had been sitting in the fire on the ground, and was nice and melted at the base. As I walked back, I swung the house bin right into my leg, which then got the side of my knee absolutely coated in melted plastic.
That, right then and there, is the most pain I have ever been in.
I kicked off my gumboot and ran to the house screaming. Luckily my mother is the unflappable type, and instead of trying to pull the plastic off or something stupid like that, she ran my leg under cold water. I still have the scar, but luckily I didn't require any skin grafts, though it was touch and go for a while.
And that was the end of me ever becoming a pyromaniac.
