Modern Family/Fridge

Fridge Brilliance: Cameron loves costume parties and dressing up Lily for every holiday, yet hates Halloween, the one day where it's normal.
In "Chirp", Jay said that Gloria likes to celebrate an anniversary for everything, including a fight she had with him after he forgot to celebrate the anniversary of their first date. In "Two Monkeys And A Panda", we find out that Gloria fell in love with Jay right after their first fight.
Jay's tendency to snark to his family. It's only when you really look at who and when he snarks do you realize he's not snarking because he's old fashion but because he just doesn't have many people in his family that share his interests and personality. Look at how quickly he became closer to Cam after finding out Cam loved/played football for instance. Likewise, Manny is willing (and wanting) to share in Jay's interests - and again, Jay becomes pretty close to him in ways that perhaps go above and beyond the call of duty.
The end result of Stella's introduction episode is apparent when you remember the Barkley the Dog Butler episode. Clearly, Jay has a thing for dogs.
In "Aunt Mommy" Claire remembers offering her eggs to Cam and Mitchell while holding an egg in her hand. Wonder what triggered that memory?
Meta one but all the special episodes that take place outside their homes like Disneyland? Well, who's the parent of the studio that makes the show? That's right, it's Disney. Which in turns means no messy legal issues when it comes to re-showing these episodes or putting them on DVD, etc.
