once you have one little nugglet of an idea, it really only takes 5 or 10 minutes to do a short 1 minute scene. If I did this once a week for another month or two, We would have some structure and deadlines (aka motivation).
The homestar runner guys have been coming up with one funny idea a week for years. Sometimes they are bad, sometimes they are ok, and sometimes they are quite hilarious. But you got to take the bad with the good. C’est la vie.
