Scribblin' - Oct 2013

Every so often, work hurts my puny brain and the urge to do something relaxing kicks in.  So usually, I grab a scrap bit of paper and draw random stuff.  (Yeah.  No need to point out the obvious fact that my work involves drawing and I'm basically working to relax.  Isn't irony oh so amusing?) 
These were October's brain farts.  If you know what any of these things have in common, please tell me.  I don't want to be the last one to find out I've predicted the apocalypse by accident.
