Clear Dad

I recently remembered this idea that I had from the days when I made skits and had my public access show. I had a commercial idea for a fake sitcom called "Clear Dad". It was about a family with a teenage son, a younger brother or two, a mother and an invisible father who didn't talk. One scene I always pictured was the teenage son with his friends in his bedroom smoking pot. In one scene, in the smoke, you would see an angry face, and all the boys would freak out. "Crap! Your dad's in here!!" That's all.
