A disillusioned laboratory animal confronts his trainer

Crap.  The stick again.  Why not the carrot?  I have been pulling this lever for hours, and no food pellet.  Why must everything shiny come with an electric shock?  Why do I never learn?  What are those funny symbols printed on the clipboard?  Where is my sugar cube?  Never a sugar cube, only a shock.   Only the wire monkey for me.  Whatever is at the end of the maze, I do not want it anymore.
