Is it silly?

I was sharing with a colleague today that many of my ideas often seem silly. We the concluded that Mark Twain might have thought "A Connecticut Yankee in King Arthur's Court" might be silly. He might have been told it was silly. Seems to have worked out okay. Southpark is silly. The Family Guy. The Simpsons was very silly in its initial incarnation as a strip in college newspapers (Matt Groenig's overnight success was anything but).
How are their ideas different than my silly ideas? They put theirs onto paper, or in production. If one fizzled out, then they went on to the next, and then the next until something hit.
We should take a lesson from their example. I am pledging to. Let's reconvene in one year. November 2011 and share what we've done.
