Under 1 MB and It Made Me Laugh!
I heard MadFlex's song and realized he hadn't submitted a Flash in six years. If he persists even now (and bothers to submit), he should be able to top this. And even back then, it must have been funny. This is what a Flash under 1 MB should be: kick-ass. It is both satirical and low-tech, an excellent combination.
If MadFlex ever decides to dive back into Flash, I would certainly welcome that moment, based on this cartoon. Why hasn't this gotten the Front Page, anyway?
