Hi Lavi,
I love writing them as they make me laugh in their creation. Strangely enough, I write them the same way I write a poem. I get a kernel of an idea that seems poetic/humorous, write an outline and then I just keep going back, editing and re-editing, until I think it's become poignant/funny.
Without the experience of 'knowing that I'll come up with something' (that I learned from writing poetry), I wouldn't even begin the posts as I never have any idea what the final product is going to look like ... or even whether I'll be able to come up with anything at all. With each, I risk wasting a whole lot of time for nothing. Somehow (magically), they always come together.
Later today I'm posting another comedy-related article (a true-story run-in with some radical feminists). It strikes me as being hilarious. We'll see. :-)
