8. Donkey Kong Monkey Action
This glitch is just a bizarre and awkward piece of video gaming history. In the original Donkey Kong made for Nintendo if you first got the Rhino named Rambi and took him to the place with the hidden silver barrel on the screen it was possible to exchange him for a clone of Kong himself. You did this by hopping off, grabbing the barrel and throwing it at a wall. When it rolled back you would hop on it just to the point where Rambi was, hop off the barrel then jump onto Rambi's back. When Rambi moves forward and destroys the barrel he will be replaced by another Donkey Kong... and the Kong you play as will ride him through the level in the most awkward way possible. To scald your retinas you can view the video here...
