Health topics. My group did one on dengue fever and abused
numbers. 
We collected data from various agencies, including WHO. Data
collected is collated into a pie chart and bar graph. Used it to
present and say that the number of dengue fever cases are dropping.
(When in actual fact it's not, that's why I said I abused
numbers)
Talk a lot of rubbish at the presentation also... like prevention,
symptoms, how has the situation improved, etc etc.
