The Shorts take a trip down memory lane with a #TBT to Y2K, when John and Joan throw a party to celebrate the turn of the century. Also, #TBT to Heather and Tim's parenting styles before they had Sophia.

Greg becomes frazzled when Lark rebuffs him and only wants to be held by Jen. Also, Heather refuses to get the reading glasses she desperately needs; Colleen introduces Matt to her eccentric father so he can get his blessing for their upcoming nuptials; and when Cousin Mikey goes through a tough breakup, Joan tries to set him up on a date.
