It can't get much crazier than
this. That is, assuming interesting might also mean crazy. Since you are a powerpoint professional and English is a problem, the best way to showcase your topic would be using visuals that convey the meaning instantly. I wouldn't risk being too graphic in a class which I do not consider safe and supportive, though.
On Channel 4 (UK) there is a funny programme called "
Will my crash diet kill me?" If the link doesn't work outside UK, youtube has some episodes so capturing some screens and mixing them, plus google should do it. Good luck! :)
