Live-action TV, I think; or possibly a film.
A character sings "Everybody dance now!" and nobody dances. So then they get serious and command, "Everybody. Dance. NOW." and everyone starts reluctantly dancing.
One of those quotations that you can't Google because you just get the lyrics to "Gonna Make You Sweat".
