What would happen, in detail, if Isaiah Mustafah ( Old Spice Guy ) and the dos equis guy fought?

Judging that the universe doesnt explode at the happenstance that these two unstoppable forces meet. Will billions of people who smell of fighter jets and the fuselage of an expensive spacecraft who are captivated by their every words, even the propositions, throughout all the parallel dimensions, and be forced to simultaneously swan dive into the best diamond studded nights of their lives? will a cake be baked so large or a dos equis so mive be brewed in a hand made dream kitchen that it is to be reveled by all? What would happen?
