Nope, I think he's dumb. He's an idiot who thinks he's smart, wastes his life on alcohol, acts like a fool, he's terrible role model for his grandson and the viewers of this show. It's sad that this is what people nowadays consider an "intellectual".
He made a dimension gun, turned himself into a pickle, made a microverse, made a universe, made a thing to erase peoples memories, killed someone by doing nothing, etc. Safe to say he is really smart.
