Paint explosion / Burning church
A friend of mine - let's call him Jacob for that is his name - is a master in the arts of DIY disasters. 2 memorable moments will stick with him forever, to be retold by any of his so called friends, including myself, for public amusement.
Disaster 1 struck when J. wanted to spray paint some scratches on his car. It was winter, and the cold paint would not stick on the cold car properly. The solution to this problem: Stick the can of paint into the oven, heat properly, retry. Unfortunately pressurized cans tend to burst when subjected to excessive heat. The can of white paint in this case exactly knew what was expected of it and thorougly exploded into a cloud of white spray paint, covering the interior of the oven and pretty much all else in the kitchen. If you have ever seen that one episode of Mr. Bean where he tries to redecorate his room with a can of paint and a fire cracker, you pretty much get the picture.

Disaster 2: J. works as a janitor at the local church. One day in summer, he was asked to remove a wasp's nest from the entrance of the church. Since the little fuckers wouldn't leave just like that, J. turned to increasingly aggressive measures, finally trying a small flame thrower / gas torch, which he pointed right into the entrance hole of the nest.
Things went as planned insofar as the wasps were pretty impressed / flamed to death.
Things also went completely unplanned, because in addition to the entrance of the nest, the entrance of the church also caught fire, which quickly spread on the bone dry wooden portal. Pure luck and the local fire brigade next door prevented a major disaster.
