Talk:Gertrude Zupermühltienatör

Is she the mother of Heinz Doofenshmirtz's father?
Remember in Meatloaf Surprise, Gretel Doofenshmirtz passes down a meatloaf recipe to Heinz's mother, thus making Gretel Heinz's grandmother on his mother's side.

Then it means that Gertrude is grandmother to Heinz on his father's side! Because Heinz mentions her being his grandmother, and hey, he can't have 2 grandmothers on his mothers side!

Then that also means that the name "Doofenhsmirtz" comes from Heinz's mothers side of the family, because Gertrude's last name is Zupermühltienatör.
