Oh boy if JP pulled some strings and worked his southern charm to get PewDiePie on for a 100th episode, that would make for a hell of a show.
Think of the children!
Litteraly, think of all the views from kids around the world.
Seriously though, it would be quite interesting, to hear of some experiences from him. mostly because i have never watched any of his content.
Pewdiepie is a great person to have on a show. His audience is horrible and not a fan of his content, but from what I've seen hes a solid dude.
I'd watch the hell out of that show.
