no, remi is just a random frenchmen. If i remember right, he got laid off from his job, so rather than looking for another, he and a friend just started fucking around with people, and filming it. And now he's famous for it.
his phrase is "C'est en faisant n'importe quoi qu'on devient n'importe qui" which means "it's by doing anything that we become anyone"
basically, he believes that you should do what makes you happy, and that doing things is what makes you who you are
