Snapped: Killer Couples (2013)

S2E46 Not Phineas and Ferb

Albert, Irving's brother, doubts that Phineas and Ferb are extraordinary, asserting his role as the "Truth Detector" to back his claim. Determined to change Albert's mind, Irving recruits Baljeet and Buford to impersonate Phineas and Ferb next to a massive hologram of the boys’ Eiffel Tower project. At the same time, Dr. Doofenshmirtz grows frustrated with his model train set's accessories and hatches a plan to shrink several national landmarks to enhance his collection.
