American Dad!

When Stan forgets his wedding anniversary - again - he arranges to have 19 hours of Francine's memory erased, but the CIA temp on duty accidentally erases 19 years. Francine, having reverted to her wild-child days, moves into her old apartment with Haley as a roommate, and ends up going to a festival with Haley's boyfriend. Meanwhile, Steve asks a good-looking girl out, but needs his wingman, Roger, to jump on a grenade for him and date her ugly cousin.
