Mario and Donkey Kong have met in battle many times over the years, but the fight always takes place on Donkey Kong's terms and on Donkey Kong's turf.  What would happen if the big gorilla challenged Mario on the plumber's familiar ground?  Here we see the result of Donkey Kong stepping in for Bowser in Nintendo's classic Super Mario Bros. as brought to us by Game & Graphics.  It's just a mock-up of course (so don't go looking for the secret code or warp zone to make this awesome scene happen), but I kind of wish that it existed in some form.  I imagine it would be frustrating as hell, but oh so worth the experience.
