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.

Episode Summary
Irving's older brother, Albert, is home for the summer and pesters his younger brother. He mocks Irving's photos of and their inventions, claiming them all to be fake, since he is so good at being a "Truth Detector". Irving decides to prove it to Albert and they agree to meet at noon in the Flynn-Fletcher's backyard. Unfortunately for Irving, Phineas and Ferb have gone to the movies for a Space Adventure marathon with their dad. So instead, Irving makes a plan to simulate a Big Idea in the backyard with the help of.

With the aid of Baljeet's hologram projector, they set up a projection of when made a replica scale model of the Eiffel Tower in their backyard. Irving is worried that his brother will see right through the hologram, since it is only a visual projection. Irving has Baljeet dress up as Phineas while Buford pretends to be Ferb. When Albert shows up, he's completely convinced by the hologram and the disguises, which surprises and annoys Irving. Even Isabella isn't convinced when she comes over, but agrees to help after Irving quietly explains. Candace spies on the boys and believes that it is her brothers down there at first, but then notices that it's Buford and Baljeet in costume. She decides to call not only her mom, but their moms as well for a mass-busting.

Meanwhile, Doofenshmirtz is setting up a model train set. He's disappointed in the shoddy work of the duplications, so he plots to fly all over the world to capture famous landmarks shrunk down to size to put around his model train set.

Albert asks "Phineas" and "Ferb" to build something for him, and they create a small crude "statue" in the backyard, "remarkable for its simplicity." However, no matter what happens, Albert is not suspicious of this being a rouse. As Albert and Irving leave, Irving tells his brother that it was all fake, but Albert is confident that it was real, so they go back to see which one's right. Isabella, Buford and Baljeet leave the backyard, taking the hologram projector with them. As they leave the backyard, Perry escapes from the trap and causes the real Eiffel tower to re-enlarge and drop into the backyard. Irving, unaware of the switch, runs right into the solid tower and is confused as to how this is possible. Albert drags Irving away, satisfied that he was right.

All the mothers arrive at the front of the house, where Candace leads them all into the backyard. However, Perry has re-shrunk the Eiffel Tower and Phineas and Ferb have returned home. Candace shows all the mothers the empty backyard, first claiming the tower got turned invisible, then pulling on the boys' faces to show that they're masks. Baljeet's mother asks if this is normal, and Linda invites them all in for tea.
