Tempted to just answer 'because' but that would be a cop out.
The entire point of this community is so that Supernatural artists and fic writers can come and indulge their random side.
Also, so that, if you do not feel like reading something depressing, you can come and find something that is interesting and enjoyable, if a little bizarre. But sometimes crazy can be fun.
We like crack!fic and crack!art. We hope other people do too.
