Energy Online: Door knocking

This funny video was created by advertising agency Contagion, New Zealand to promote Energy Online, an atypical energy provider.
The tagline is “Door knocking is so last century. See how we got rid of them.” and it fit very well with the movie.
The commercial is a funny prank and even I know it was made with actors, I like it for the idea.
In just a few days, the ad becomes viral.
