On my first world in Minecraft, I was playing with flint and steel (Remember back in 1.2, Fire wasn't nerfed). So I wanted to eradicate one tree in the forest to create a new house, and practically a few minutes later, I was like FUCK! FUCK! SHIT! Arceus DAMN MOTHER FUCKING TREES! All the trees were caught on fire :L. I spent the last 3 hours trying to clean it all up, gaining like 20 stacks of wood in the process. If you check out my first world, there are still remnants of burnt trees, some of them are still caught on fire.
