Carly and martial-arts champ Shelby Marx (Zoey 101's and Spectacular!'s Victoria Justice) agree to have an exhibition fight for charity after Carly jokingly challenges her to a match.

Carly visits Shelby and apologizes, and the fight is back on.

Shelby, furious, attacks Carly for real during the match, Carly then holds Shelby's leg for the rest of the "fight".
