I have my own chilling tale of pyromaniacy:

I walked into my parents bathroom as a child and my brother (the older one) was
spraying lysol on the counter. That seemed normal at first, but as I continued to watch,
he did not stop. He kept sprayng until a large puddle had formed (since the counter was concave). He
lit a match he had took from the kitchen and threw it down on the counter, and suddenly our
bathroom was ablaze! Fortunately it stayed within the bounds of the puddle, but he
didn't keep it that way much longer. He the can of lysol again and sprayed it into the
fire then pulled back and made a trail of flame in the air! I
watched in amazement as my dad kicked his ass later.
