YouTube Popularity Experiment

I have published many videos on YouTube. The most popular one (in fact the first one I ever posted) was only viewed ~1,750 times. I'm not having delusions of grandeur, but I was wondering what sort of video could be more popular? Obviously if it's original content then that would mean personal success. However for the sake of this experiment, what subject would quickly attract viewers? One evening I was watching David Letterman and the answer struck me. Two words: Paris Hilton. (Forgive me: I never thought her name would be perpetuated in my webspace. I have my own...arhem...negative opinion on her rise to 'fame', what she symbolises in this age, etc, etc - but that's not the point of this experiment.)

I posted the following three videos (rather funny excerpts from Letterman). The first of the videos' view count quickly shot into the mid-thousands and now has come to relative rest at 20,000! That's popular culture (and many other things) for you.
