New Phineas and Ferb theory on Doctor Doofenshmirtz, and his wicked family's mystery.
Today we're focusing on José Doofenshmirtz, grandson of the devious Dr. Jekyll, grandfather of Heinz Doofenshmirtz, yet somehow the only member of the Doofenshmirtz Family who’s Latino.

Several clues scattered throughout the show hint at a mystery that explains his connection to the Doofenshmirtz lineage, and his Latino heritage at the same time. PLUS, today I’ll also prove to you guys that Dr. Doofenshmirtz himself is actually related to one of Phineas and Ferb's closest friends. You curious? Yeah, no, me neither, whatever.

This is a story about seduction, cheating, kidnappings, and apparently corn and meatloaf as well. This is the Grandpa Doofenshmritz theory. Join me in today's video and share your thoughts on it! :D
