This should be an episode:
Doofenshmirtz: Haha perry the platypus, ever since I was a little boy back in gimilshtump, my parents would always give my brother Roger all the ketchup when we had fries, so now everyone in the tri-state area shall eat only heinz doofenshmirtz branded ketchup. You see, I have made the ketchup-brand-intator that will make every bottle in the tri-state area have the name Heinz on it. But first, I shall zap this local convenience store to show you its true power
Perry the Platypus: *stares at him*
Doofenshmirtz: What is wrong, you seem a little off today, is it because of my-wait, these stores already have Heinz Doofenshmirtz-branded ketchup on it. Huh. You can leave now. Curse you Perry the Platypus I guess.
