The Fairly OddParents - 2x01a - Boys in the Band

Timmy is mad at Dimmsdale's singing sensation Chip Skylark for holding a concert on Timmy's birthday, causing everyone to ignore his existence, even his parents. To get revenge, Timmy wishes for the worst non-lethal thing possible to happen to Chip: he gets held hostage by a crazed fan, Vicky. As the crowd at the Dimmadome grows more and more restless, Timmy realizes that Chip is not so bad after all, and decides to wish him free. Unfortunately, Cosmo and Wanda can't, because Vicky has fallen in love with Chip. Timmy must find a way to break up Vicky and Chip and get the singer to his concert before a rampaging crowd of angry girls, and Timmy's dad, destroys all of Dimmsdale.
