It was a well drawn and well animated short. The characters look just like Penn and Teller, which is a token of merit for your skills. The joke to the Flash is understandable because everyone knows Teller doesn't talk, but it wasn't funny at. The Flash didn't establish an emotional connection to the audience, therefore, the viewers aren't able to project themselves to the characters. And that component is KEY to any story of all mediums. If there's a lesson to take from this, it's to run the script passed like-minded peers and rewrite to make the story stronger.
