As the series wraps up its second season, it rewards regular viewers by referring back to episodes from last year

ABC
We've known the Modern Family gang for two whole seasons now, and we finally have some inside jokes. The finale of this season was packed with references not only to this year's episodes, but also to moments in season one. It made me feel like I really knew the Dunphy-Pritchets, like we're at that point in our relationship where things just click.
It's Jay's birthday, and after last year's hectic affair—Gloria invited the entire family on their romantic getaway to Hawaii, and chaos ensued, obviously—all Jay wants is to spend a quiet day fishing. As Jay heads out, the rest of the family preps for his birthday celebration. Claire and Mitchell, presumably getting a little inspiration from the Internet, decide to recreate a childhood photo of them in their old backyard. Cam is supposed to get the fancy bakery cake. And the Dunphy kids are finishing up a video montage of the family.
That all sounds peachy. But, of course everything goes all wrong. Claire and Mitchell get chased up a tree house by a dog. So instead of getting the shot, they get wasted with a bottle of wine Phil and Claire had purchased for Jay's birthday. And awkwardly discuss their inferiority complex to Manny.
