Tim and Heather unintentionally make things incredibly awkward for Tyler when he brings his gorgeous new girlfriend, Clementine, to meet the family. Also, Matt and Colleen are caught canoodling at the office by their obnoxious co-worker, Will, Jen and Greg vow not to become germaphobes, and John buys Sophia a cell phone behind her parents' backs.

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.
