David broke his arm because he fell on a dog, which is already quite silly. The hospital applied a resin cast. That same evening he went to a party and after a few hours and a few drinks, friends found it funny to customize David's cast with imaginative pornographic drawings. The next morning David's mother discovered the artwork. After his father stopped shouting, David--who is not exactly the DIY type--tried to erase the shameful drawings with 'white spirit'. He didn't realize that this corrosive product would spread through the resin gauze and burn his skin deeply. After a few hours of abominable pain, David decided to break the resin with a hammer. He did it well. He broke the cast and managed to break his arm in another place!
Thank you for giving this submission the attention it deserves.
