On our prior location, while watching TV at dinner time, a new TV commercial about a local cable company offering HD content was shown. It was a mock of a director wanting more of the actor as he was set on fire. The crew laughed and pointed at me for they say I'm always asking for more risk and more intense realism for the film, so we decided to make a parody of it using archetype grumpy director attitude and using footage recently shot of the Cochrane's bunker.
Ended up well. Silly but funny :)
