The reasons why we should use MS paint:
1) not everyone have any kind of advanced art programs so MS Paint is already in Windows (sorry, I don't know about Mac lol)
2) for those who can only draw a stick man can take advantage to create something good and funny with simple and sloppy drawings on MS Paint.
Anyone can win for $30 on a sloppy but creative works!
*(If anyone really want to use photoshop or any kind of graphic programs for next contest, we can discuss about that in some time future.)
