Cadbury Dairy Milk 'eyebrow dance' by Fallon

The TV ad is the third in Fallon's "Glass and a Half Full Production" series and focuses on two kids, a boy and a girl, doing some crazy dancing with their eyebrows - backed by the 1989 track Don't Stop The Rock by Freestyle.

The ad begins with the pair posing for a photograph. When a phone rings off-screen, the photographer disappears. 

As the music plays, their eyebrows dart up and down in time to the beat, before the girl finishes the routine by letting air out of a balloon.
