This morning on "Today" we got to see just how massive the show's staff is -- when they made a huge one-take video to the Black Eyed Peas' song "I Gotta Feeling."

Showing everyone from anchors to make-up and PAs, the video snaked around the show's studios and out into Rockefeller Center!

Our favorite moments: Kathie Lee & Hoda Kotb sipping on wine ... and Brian Williams' bizarre backwards dancing!
