13. Poor Little Rich Girl

Zack and Cody watch a video of them being born, but in the video, their mother might have mistaken them for each other, so they become the complete opposite of themselves. Meanwhile, London becomes poor after finding out her father went bankrupt from a failed investment of diamonds, so she stays with Maddie until her father can find a place for her to stay. At the end of the episode, Carey gets her sons' birth certificates from the hospital and tells which of her sons are which. Also London becomes rich again when Mr. Moseby tells her that her father struck oil in his diamond mine. Guest stars: Estelle Harris as Muriel, Adrian R'Mante as Esteban
