PARKOUR means progressing forward in the most economical way possible, with no boundaries.  PARKOUR means never looking backwards    First, know your subject.  List ALL its actions, good & bad. All its results, its inputs, its users.  What are the common assumptions & habits of this genre?  Start with the top 3-5 assumptions and habits in this genre.  Write them down, then INVERT. Next to each action, each user and each assumption try the opposite.  This is where it is of utmost importance to ignore your inner expert and apply all your knowledge and experience to making the inversion real.
What happens when you disrupt the status quo?  Why couldn't that work?  Parkour!

Parkour is not often funny - after all it requires serious concentration.  But this clip from The Office below is hilarious with its everyman version.
