A lot of great satirists take something ridiculous and present it with a straight face.
What is the stupidest, most ridiculous thing about bullying? How can you show the flaws in it through a story or essay?
Your subject reminds me, in some ways, of the ancient Greek satire "The Clouds." In it, the physical embodiments of two styles of debate have an argument over who is more gay. They conclude that the audience, in fact, is the most gay. They even point out certain members of the audience who most possess the qualities of a homosexual. It's a pretty crazy play, and it was written in 423 BC!
Edit: I just want to clarify that in "The Clouds," the term 'gay' (as translated in the copy I read) is not used as an insulting term... it is used to describe homosexuality as seen at the time (which was two adult men). I would not have written about the play if it were insulting to homosexuals.
