Here are a bunch of clips from Stephen Lett in 2003 in Sydney (I actually went to this convention)
Apostates: http://www.youtube.com/watch?v=DnnKU4FyTVE
Media: http://www.youtube.com/watch?v=7HOuNs8I8gY
Women: http://www.youtube.com/watch?v=lKuEUzLp7lY
Internet: http://www.youtube.com/watch?v=MKbARrjEYko
School mates: http://www.youtube.com/watch?v=1FnlUZlCJas
I liked the school mates one. Just think about all the examples of Jehovah's witness children that are encouraged to conduct bible studies and witness to their school mates and change their beliefs whilst you listen to that one.
