I understand that the humor of this is supposed to be the over-the-top meme things, but in reality everyone would rather have the mambas.
People have killed mambas with their bare hands, nobody's done that to a gorilla. Plus, I don't think snakes can climb. If you were to go up a flight of stairs it's entirely possible that the snakes wouldn't think to go up. The gorilla on the other hand? He's semi-intelligent and searching the place.
