Phineas and Ferb - Season 2 - Eps 46: Not Phineas and Ferb
Irving’s brother Albert doesn’t believe that Phineas and Ferb are anything special, and since he claims to be the “Truth Detector,” he can prove it. Desperate to prove Albert wrong, Irving convinces Baljeet and Buford to pose as Phineas and Ferb beside a giant hologram of the boys’ Eiffel Tower construction. Meanwhile, Dr. Doofenshmirtz is fed up with the quality of accessories for his model train set, and decides to shrink down a variety of national monuments to add to his collection.
