At the start of the episode, we see each of the three main couples in separate interviews with the invisible documentary maker. In proper documentary fashion, the couples get title cards identifying their names, and the number of years that they have been together — except for Cameron and Mitchell.
While Jay and Gloria and Claire and Phil got title cards, Cam and Mitch did not get one, and had to verbally tell the audience that they had been together for five years up to that point. Some fans thought this was an oversight on the part of the show's makers. But it was actually a deliberate choice, and a subtle clue about the challenges facing Cam and Mitch.
Back then, gay marriage was still illegal in the area where the entire extended family lived. And so while Jay, Phil, Claire, and Gloria could flaunt their married status in the title cards, Cam and Mitch could not, since they were not technically married. Fortunately, fans did not have to wait forever for the two lovebirds to be legally allowed to make things official. Cam and Mitch get hitched in the finale of the fifth season of the show.
