I did one of these for my 11th grade english class once. meaning that i wrote an essay in the same style- just totally off track and bizarre. Needless to say the teacher wasn't terribly amused, and i got points off for quality style and substance. Still got a B- from the good grammar though.
the second one was definatly the best. the last one's kinda funny to, esp with tupac and biggie smalls.
