Basically, a door on temple_classic achieved sentience and started proposing a lot of new game ideas. Mangley thought that these ideas were really good, so he murdered the door and took the ideas for himself. CCsaint saw this and mourned for the door but was forced to keep quiet about the whole affair because everyone would think he was insane if he spoke about it.
Anyway, the barrels never have any good ideas so I'm not sure why Mangley brought it up.
