street performer 
If you stroll through the streets of Copenhagen, you will meet a lot of street performers, who entertain the passing people. They masquerade as kind of historical characters or statues. They stand still without any little move.
But suddenly, without a warning, they wave a hand, swing their sword or do anything else to startle someone, passing or watching to close.
That´s the moment, the public awaits gratefully...:-)
Afterwards some coins fall into the provided box.
