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.

John and Joan disagree with their neighbors, Jerry and Pam, about who gets to use the hot tub when new property lines are drawn. Also, Greg and Jen invite their exterminator and his wife over for dinner, Matt and Colleen make an effort to be friends, and Tim is terrified to perform minor surgery on John.

Dinner gets awkward for Jen and Matt when they find themselves alone without Greg and Colleen. Also, Lark accidentally locks out Greg and Jen from the house, prompting Greg to install a complicated home automation system; Heather and Tim try to sneak wine into an ice skating show to get out of paying at the venue; and John and Joan agree to an impromptu wedding after Colleen mentions that she's an ordained minister.

The holiday spirit is alive, well and wildly different for each member of the Short family.

When Tim gets a toupee, the family try their best to hide their horrified reactions; Jen fights for face time with her boss; Joan decides to retire; Greg and Matt build a playhouse for the kids.
