Phil is determined to help Luke prove to mom that he is responsible enough to have the brand new bike they just got him. However Phil ends up being the irresponsible one when a hot neighbor clouds his judgment. Meanwhile Mitchell and Cameron take Lily to their first Mommy & Me class, and Jay and Manny have some awkward father and son time.

Phil pushes Jay to go out with him and fly his new model plane. While Manny takes time out to play with Luke, Gloria accompanies Alex in shopping for a dress. Later on, Manny ends up having a heart-to-heart talk with his sister Claire.

Claire and Mitchell's mother, Dede, drops in for a surprise visit and is determined to make amends with everyone she offended during what has been deemed "the incident" at Jay and Gloria's wedding. Needless to say, no one is thrilled to see her and everything comes to a head when the whole family shows up to dinner at Claire's house.

The whole family is invited to Jay and Gloria's for some barbeque and football. However an earlier incident at school between Manny and Luke makes things very awkward for Gloria and Claire, and then things escalate when a not-so-flattering label is uttered.

It's the first day back at school for the kids and, at the Dunphy house, Phil oversteps when he misreads how Claire is coping with an empty nest. Over at Jay's, he and Gloria are in disagreement over Manny's interesting choice of outfit for his first day of class, and Mitchell and Cameron freak out after Lily gets her first bump on the head.

The whole family comes out to support Manny's newfound interest - fencing. It turns out he's quite masterful in the sport, but Jay's proud enthusiasm triggers an old childhood wound for Mitchell. Meanwhile Phil is determined to find where Luke's hidden talents lie.

With a history of giving bad gifts, Claire is determined to surprise Phil with an amazing anniversary present: a private performance by one of their favorite musicians, Izzy LaFontaine. However, it turns out to be unexpected in more ways than one. Meanwhile, Mitchell and Cameron call up their "party-girl bestie", Sal, for a long overdue night out on the town.

Nothing is too big when Phil and Claire decide to throw Luke the biggest and best birthday party a boy could ever want, but when Cameron shows up as Fizbo the Clown, it sets off a chain of events that ends with someone in the hospital.

Christmas is in full swing at the Dunphy house until the kids get in some trouble and Phil and Claire threaten to take away Christmas until one of them fesses up. Meanwhile, Jay struggles with wanting to stick to his holiday traditions while Gloria and Manny want to incorporate some of their Colombian practices, and Mitchell and Cameron take Lily to the mall for her first picture with Santa -- but end up with a disgruntled mall Santa on their hands.
