User blog comment:Kuzlalala/Lala's Long but Orderly Put Theory about Phineas and Candace's Biological Father/@comment-4037231-20110809025353

I have my own theory, just bare with me.

Years before the show, Doof had started in evil, so he needed a robot serveant. After Sarcastic Norm failed. Doof kidnapped a man and turned him into what we now know as norm. That man, was phineas's father.

Shut up.
