Not fanservice. Alex said that they planned on Stan having a secret brother since episode one. He wasn't much of a secret, was he? I mean, Stan IS a 'gruncle', he has to have a brother who is kids' grandfather.

Which begs for another question: is Stan's brother their grandpa? Or another gruncle? Not really no, plus people have been theorizing his existance since Carpet Diem.

And my theory on it, is either Author Stan IS the grandpa or Grunkle Stan is. How crazy would that be?
