Argument
My plastic ruler has more charisma than Keanu
Rebuttal
Well, I'd say that's a bit unfair. Most humans – heck, most mammals – can hardly be expected to be as charismatic as a flat stick of plastic with little lines spaced out on it in a manner most pleasing to the eye. So, yes, you win this one, but it hardly says anything about Keanu's level of charisma by human standards, which I believe is sufficiently adequate and more than that of many others of his species.
