The Kiss is the eighth episode of Season 5. It aired on December 3, 2013.
When Frankie's sister asks her to house-sit, Frankie and Mike jump at the opportunity to have a romantic, kid-free weekend in an upscale home. But technology might just trump romance when they find themselves having difficulty navigating all of the computerized gadgets in the house. Meanwhile, Sue, who has been left in charge of watching over Brick while the parents are away, finds the Heck house being invaded by the bratty neighborhood Glossner kids, and Axl takes a road trip with Darrin and Sean in an attempt to drive to Vassar and reconnect with his ex-girlfriend Cassidy.
- Sue says that she's never even seen Mike and Frankie kiss, but in the season 1 episode The Floating Anniversary, while Mike and Frankie are kissing, Axl and Sue walk in the room and Sue said "I think old people kissing is sweet."
