One is a gigantic, anthropomorphic gorilla that flip-flops between hero and villain willy-nilly according to the demands of the company that owns his hairy, flatulent ass, and the other is Donkey Kong. Literally the only way to tell the two of them apart is by offering them a banana. Donkey Kong will accept the banana and then share it with his girlfriend, Candy Kong. The Big Show will cry, and then inexplicably turn heel, turning babyface again before the night is over. Also, Donkey Kong has more chance of winning the Royal Rumble, and hes never been booked in it.
