S4E15 Candy Wars

Kady is eager to bond with her dad, so she recruits Michael to assist with the school candy drive. However, when last year's champion's father asserts that he can win again, a competitive streak ignites in Michael. He becomes so focused on outdoing the competition that he loses track of his original goal: to support Kady, diving headfirst into selling an overwhelming amount of chocolate bars.
