Major Monogram: Sorry, Phineas. It isn't safe. You know too much.

Phineas: Now I never wished so much that I could un-know something.

Carl: Sir, maybe there is a way. What about Dr. Doofenshmirtz's Amnesianator?

Doofenshmirtz: I never built an Amnesianator. I think I would remember building something like that.
