Dollars and No Sense - S1.E8

Freddie decides to override Sofia's judgement by buying Zoey an expensive phone that she wants. When they are caught, Freddie and Chris are supposed to take Zoey to a soup kitchen to teach her a lesson, but instead decide to take her to an auction that they'd been planning on going to. The real lesson is learned when Zoey makes Freddie bid a ridiculous amount of money on an item she wants, and Freddie makes her work it off at the restaurant, finally teaching her the value of a dollar.
