The story opens with Phineas, Ferb, Candace and their father Lawrence going to see The Mummy with Two Tombs at the Pharaoh Theater. "You couldn't pick a better place to watch a classic old mummy movie." In the movie, an explorer reads the hieroglyphics carved into the wall. The incantation is "Owa Tagu Siam" (can be interpreted as "oh what a goose I am" because of the pronunciation). Phineas asks Lawrence where you can find a mummy. "Hidden deep in the bowels of the pyramid", is the answer. Meanwhile, the explorer learns that the incantation will bring the mummy back to life and obey commands. He exclaims, "Well, beat me with a chicken!" The mummy grabs a chicken and proceeds to beat him with it.
Phineas, Ferb, Candace and their mother, Linda are watching television around the breakfast table. A commercial comes on announcing there will be auditions held for The Next Super American Pop Teen Idol Star at the Googolplex Mall. Candace is extremely excited and rushes upstairs to call Stacy with the good news. Phineas says that being a pop star would be fun at first, but would then get dull quickly. He laments that there isn’t a way to do it just once and quit. Mom explains that he is talking about a one-hit wonder. A flashback reveals that Linda Flynn-Fletcher-Fletcher was once known to the world as Lindana. Her song I'm Lindana and I Wanna Have Fun! rose to the top of the charts - but she immediately threw a diva tantrum and her song soon became elevator music. She sang one reunion concert years later and never sung again. She denies to the boys that this has happened, but has nonetheless inspired them. Phineas scribbles out a checklist of the steps needed to become a one-hit wonder. They now know what they’re going to do today.
