If DPJ is faking that voice then I would take the piss out of him because it is a bit silly sounding. But if he is not and he actually has that lisp then I think its great that he is not embarrassed to show it whilst making stuff he enjoys doing. He has that many subscribers because he does do good videos with decent information. But lets face it he is always going to get ripped for his voice, he knows this and probably doesn't care. Had it his all life I bet.
