Straight-up Bust

 is a song performed by Candace in "Imperfect Storm". It's sung when she overhears Linda on the phone saying that the two landscapers she hired are ruining her garden, but Candace thinks Phineas and Ferb did it and Linda busted them (due to Linda calling them "the boys").

Continuity

 * This is the fifth song about busting Phineas and Ferb. (Busted, Bust Your Brothers, You're Going Down, Pic A Nic Bust)
