Stitch's Sudden Rampage

In the Stitch! episode "Angel's Flight", Stitch and Angel are enjoying their time together, with Angel singing her siren song, "Acoota Chi-Meeto". Normally, her song doesn't affect Stitch the same way that it affects experiments made before her, but her developing head cold makes her beautiful singing voice become hoarse. Her changed voice somehow DOES affect Stitch, unintentionally brainwashing him to follow his evil destructive programming and go on a rampage around town on Izayoi Island. He only stops when Angel headbutts him, which knocks him out cold. "Love hurts" indeed, Pleakley.
