We are an imperfect people. We make mistakes. One such imperfect person was riding a motorscooter and plowed into approximately 20 traffic pylons before wiping out. Another such imperfect person was recording that. Presumably a third imperfect person thought it would be funny to add Mario sound effects and post int online.
I am the fourth imperfect person, passing it onto you. You will be the fifth, Whoever you show is the sixth. And so on.
