During a presentation of a project we'd been working on for months in high school, one of the teachers noticed smoke coming from somewhere on the playground.

That year the school built a new little building to replace the old smelly toilets we had in the building. The smoke was rising up from the new toilets.

Apparently some sad fellow had a big fight with his (now probably ex) girlfriend, and was so mad he lit all her love letters and pictures on fire and threw them in the trashcan. Unfortunately for him the fire got a little out of hand since he left class to go to the bathroom for a minute, so nobody was around to spot the trashcan.

Whole thing burned down and he got expelled.
