That's this _century's_ Dennis the Menace. That's what made it funny, back in the twentieth.
As Aaron pointed out, Mr. Potter was the main influence. And possibly Conrad Bain.
I always thought he was supposed to be (prepare for severe name-butchering) Bob Ueuker.
Everyone says that about every Comic Book Guy. That's why it's funny. And why FOX could never sue Amblin's "Animaniacs" for its Steve Putner character.
Again, it's Bobby Kennedy.
I'm glad I'm not the only one to see this.
