Principal Fink suspends Larry from school for 30 days when pot is found in his jacket pocket, although it's actually Dave's jacket, which Larry wore by mistake. Dave tries home-schooling Larry, but first he and Vicky talk to a priest about enrolling him in parochial school - the same priest Mike thinks is hitting on him.

The kids are excited about the school's Sadie Hawkins dance, and even Kenny has a date. Once word gets out that Kenny's planning on attending with another guy, he and his date are barred from the event for not keeping with the Sadie Hawkins tradition. An outraged Larry stages a protest against the discrimination, and Dave goes to the school to argue Kenny's case. Once Principal Fink (Martin Mull) finds out that Kenny has been living with the Golds, he informs Dave that he's obligated to tell Child Services, and that Kenny will have to be put in foster care. So Dave tries to get Kenny's parents to let him come home.
