Evidently someone got bored, as a couple of people appeared on air dressed as sheep and started setting up dominos. Various Bert dolls and green monkeys were waved at the camera. Dramatic movie music was played. I think it might have been from Lord of the Rings, but I dunno.
Then one of the sheep people swept up the dominos with a broom, and now he/she is dancing with the broom.
I wonder if someone at TV4 brought some illegal drugs in to work. Whatever it is, it's as odd as hell.
