At last, "This Is Us" Season 3 is filming. Better still, the first day back, July 10, brought some fun photos and video from the cast.

Based on what we've seen on social media, the cast and crew were just as excited to get back to filming as fans are to see them do it. Leading up to their new beginning, star Chrissy Metz said it felt like "the night before the first day of school" and shared "gratitude for each one of you who are as excited as we are to share these new chapters together."

And that was only the beginning. There were numerous posts from her co-stars and the crew on July 10. Let's start with our favorite: a video tweeted by Sterling K. Brown that shows him making the most of Day 1 alongside his onscreen wife, Susan Kelechi Watson.

Brown and Watson doing the Shiggy? Yes, please. When the co-stars weren't dancing around on set, though, they were hard at work. Both actors were in the first scene, which we know thanks to a photo from "This Is Us" creator Dan Fogelman.

Brown and his co-stars later had a lot more to say about the day. Clearly, they were happy to be reunited and resume work on the hit NBC drama.

"This Is Us" returns to NBC on Sept. 25 at 9 p.m. ET/PT.
