''Tableau Vivant'' (season 3, episode 23)

''The rare moment that we all get to come together as a group and do a big ensemble scene — it's the most fun on set, and it happens a few times a year. That was one on my favorites: There's just something about having to sit frozen in that painting and have this argument under our breaths. Everyone really held their own, and even Aubrey [Anderson-Emmons], our little Lily, was in that scene, pulling her weight. It was such a great image of all these people slowly cracking and having this argument under their breath. Our art department should have won an Emmy for that episode. It was so beautifully shot.''

Modern Family's 100th episode airs tomorrow at 9 p.m. ET on ABC, with reruns weekdays on USA.
