What does a humorist do when he runs out of ideas? He can bemoan his lack of ideas and shed copious tears all over a blog post. Been there, done that in the "Lament of a Jester". What other options does he have to keep writing?
Well, if one cannot write humor the next best option is to write about it. After all, hasn't someone said that "If you cannot do it, teach it"? So, there I go talking of the various forms of writing humorous fiction with no more than a reader's perspective of writing.
I have, at least, illustrated the various forms by essaying examples in writing the story of "Troy" humorously. I am sure you will find it funny - either the humor or the fact that I thought this was humor.
