While playing games at her house, Steve finds out that even her father is on board - once he meets Steve's parents. Desperate for a crack fix, Stan tries to steal from the family and then offers to perform an unnatural act on the father, ruining Steve's chances. On his way out, Jeanine demonstrates her flexibility, making things even more painful for Steve who says he will hate Stan until the day he dies.
