Below is Labour's mocking of the Tories, depicted as incompetent and unprepared. I found this piece produced by TangentOne, Labour's agency, nicely done and fun, which means that it has a good of virality. Furthermore this is an example of "viral with a purpose", or viral that produces value (see Godin's quote) for the "brand" making its case to the "consumer" / voter. Also, an additional indication that early elections may be called in Britain. Enjoy!
